* BadassDecay:
** In Season 8, Flora seemed to be one of the better drivers initially, and both viewers and the show's judges alike predicted that as soon as her husband Frank stopped acting like a {{Jerkass}} BackseatDriver, she'd massively improve and quickly graduate. Unfortunately, her performances actually got ''worse'' as the season progressed, and seemed to show no real correlation as to how Frank behaved or whether he was even in the car, resulting in her being named the joint-worst for the season alongside Kevin.
** Sly went from a near perfect final drive in Season 7 and a promise not to drive distracted to a terrible performance in Ever. Ultimately DoubleSubverted when he had a great roadtest once again.
* Jillian from Season 11. She had the best technical skills out of all of the nominees, and could have graduated early, but she stayed on. Unfortunately, her performances dropped in the second half, and she couldn't get the confidence to drive on the roadtest.
* EliminationHoudini: An unusual example of this trope, since being eliminated from the show is a ''good'' thing:
** Billie-Jean from Season 3 was shortlisted three times ''in a row'', yet there was AlwaysSomeoneBetter each time. On the fourth occasion of her being nominated she nearly failed to graduate again, as the experts thought that Shelby had done better in the episode, but Andrew persuaded them that it was time to let Billie-Jean go.
** Ashley from Season 4. She was shortlisted to graduate four times, and still was named Canada's Worst Driver. She was an unusual case overall, since it was obvious to everyone that she was a ''way'' more skilled driver than runner-up Emily, and in fact most of the drivers from her season; the real problem was her inability to get on with her husband while driving, something which neither made any real attempt to improve (frying the alternator on ''Andrew's own truck'' in the final road test didn't help much either).
** Father Giles and Jakob, the third-last and second-last graduates from Season 5 were each shortlisted three times before eventually leaving, which in both cases was further delayed by no-one graduating in the fourth episode, and then Crystal having to pull out during the following episode.
** Season 7 saw a rare ''deliberate'' example of this trope, as Aaron could have potentially graduated by about the halfway point of the season. However, he was determined to stick around for the whole season, mainly because he wanted to take part in the final road test, which would prove once and for all that he could drive again.
** Diane from Season 8 was shortlisted every second episode, but was ultimately the last person to graduate, in part due to her twice refusing to graduate, and also due to the panel inexplicably deciding that Margherita should graduate over Diane in the penultimate episode.
** Michael from ''Ever'', who managed to tie Ashley's record of 4 nominations without graduating... including being shortlisted three times in a row, much to his dismay. He would probably have graduated in the fourth or seventh episode, if not for Angelina being forced out due to her mental health issues in the former episode, and Dale being kicked out of rehab for attempting to quit and injuring herself in the latter. He was the final graduate of the season, however, after a nearly-flawless public drive (while Sly had a flawless public drive, he did so badly on the challenges throughout the rest of the season that Michael was given the final graduation instead).
** Siham from Season 10 was nominated several times as the season progressed, but kept narrowly missing out and ended up in the final episode. In her case it was mostly because while she was quite capable technically, she had major issues with confidence and kept relying on her husband to make all the decisions. In the end she didn't actually graduate as such, but did get easily the most positive edit out of any runner-up... not that this stopped her from dropping a ClusterFBomb or ten on Facebook and Twitter, over the fact that Jason was graduated over her.
** Jillian from Season 11 wasn't actually nominated at any point prior to the final episode, but could probably have graduated at any time she wanted, as she passed the majority of challenges she took part in (including every challenge in the second episode), and was considered the season's best driver from day one. However, she kept passing up the opportunity to graduate on the grounds that she still needed to address her severe anxiety, eventually resolving to take part in the final road test. Sadly, her nerves proved too severe, which prevented her from taking the road test and caused her to be named the worst.
* EnsembleDarkhorse:
** While Andrew is definitely the star of the show, Cam is almost as popular thanks to his straight-talking nature and lack of any hesitance in calling out people who offer up any form of bullshit.
** Michael from Season 2 and Shelby from Season 3 (both of whom came back for ''Ever''), for both being all-around nice guys who always take full responsibility for their mistakes. Michael's ability to drop pertinent comic and sci-fi references into any situation may also help.
** Season 5's Father Giles, for being the epitome of a CoolOldGuy, and even praying with Crystal immediately after she found out that her brother-in-law had been killed in a traffic accident.
** Paul from Season 6; despite being a stereotypical BadassBiker and tough guy, he proved calm, capable and a very adept learner.
** Season 7 had probably the show's two all-time most popular contestants: Aaron and Shirley. The former for his backstory, his desire to make sure his own accident counted for something in helping others (even if it meant being named the worst, which he ultimately wasn't), and his overall performance on the show. Shirley's popularity was thanks to her consistently positive attitude and passing more challenges than anyone in the show's entire history, something that wasn't at all diminished when she got named the worst thanks to a horrid road test. Her darkhorse status was only further cemented when she came back for ''Ever'' and graduated second after a virtually flawless performance.
** From Season 8, we have Diane. She started off not caring about whether or not she would be named "Canada's Worst Driver", but really [[TookALevelInBadass improved a lot]] over the course of the season, and present what Andrew considered [[NoDamageRun the best road test the show has ever had.]]
** Season 10 had a somewhat unusual example of this trope. While the season was actually airing, Siham was by far and away the most popular contestant with the fans, who viewed her as the DistaffCounterpart of Aaron, and it helped that she generally did well in the challenges. That all changed the day after the finale aired, when she went ballistic on social media, aiming some incredibly nasty insults at the people involved with making the show, and even some implied legal threats.[[note]](While she was vague about what exactly upset her, the general jist of it seemed to be that she was ''very'' pissed off that Jason was given the final graduation instead of her, and that Cam had tried to name her the worst driver. Many of the show's fans actually ''agreed'' that Siham should have been the final graduate, but the way she handled the issue unsurprisingly turned people off of her)[[/note]] Instead, Santana is now generally regarded as the season's Ensemble Darkhorse; while an early graduate, she was also perhaps the best performer aside from George, and definitely had the best attitude toward learning.
** Season 12 has Mike, who had suffered a brain injury (like Aaron) turned UpToEleven (which was he had to ''relearn everything that he had ever learnt in his life'') and his commitment to learning how to drive again, despite the numerous accidents since he gotten .
* JerkassWoobie: Angelina. ''Dear God'', Angelina. She may be ignorant at times, and show a lack of improvement but her depression, anxiety and overall mental health problems are almost enough to make her a straight example of TheWoobie. Her boot episode in Ever shows just how damaged the poor woman is.
* MilestoneCelebration: Counting the specials, the 100th episode was the penultimate episode of season 12. Andrew's monochrome lamenting of this fact [[MoodWhiplash is interrupted by a full color marching band celebration.]]
* RescuedFromTheScrappyHeap:
** Arun from Season 5. He was ''not'' liked by most viewers at first, especially during the fifth episode when he displayed blatantly sexist behavior toward his wife and nearly caused about a half-dozen accidents in the lane changing rally. However, the news that fellow contestant Crystal's brother-in-law had been killed in a motoring accident later in that episode really seemed to shake him up, and after that he took rehab a lot more seriously, started behaving more reasonably toward his wife, and became the season's final graduate.
** By extension, Crystal herself. Prior to her brother in law dying, she was probably the most ignorant driver in rehab, but the news gave her a rude awakening.
** Two examples in Season 8 -- Klyne started out looking like another young driver who didn't give a crap about improving, in the same mould as Colin or Scott, but he took the rehab process seriously and ended up being the third person to graduate. In fact, he could have been the ''first'' person to graduate, but actually turned the opportunity down, feeling that he still had a lot more to learn. Also from that season, Margherita was probably the worst driver (other than Kevin) in the first half of the season, and initially didn't seem to care much about improving (largely due to her nominator constantly telling her that the experts were dumb and to disregard their advice), but she eventually took the lessons on-board and improved significantly over the course of the season, eventually becoming the penultimate graduate.
** Angelina in ''Ever'' was received with much more sympathy and concern after she left the show for mental health issues.
** Mariah from Season 10 was an early favorite to end up as the season's worst driver, due to her lackadaisical attitude and unrepentant admission of drink-driving. Over the course of the season she made a genuine effort to improve, and fully redeemed herself by getting a "no drinking and driving" tattoo on her arm when she graduated.
** Jordan from Season 11 was hated for his self centered attitude, and lack of interest in the rehab centre early on. However, he managed to fix his main problems (eye sight, driving distracted), and developed a better attitude for learning, earning his graduation by Episode 6.
** Tyler from Season 12 would have been easily the most-disliked driver in any previous season (Krystal easily outshone him in that regard this year), due to his generally oblivious attitude and admission of habitually drinking and driving. However, he made a real effort to improve over the course of the season, was treated more sympathetically by fans after it was revealed that he had sustained a brain injury several years prior, and finally redeemed himself by doing well in the last two episodes, becoming the season's final graduate. Even the aforementioned Krystal's nominator, Steven, said that watching Tyler's journey had made the season worthwhile despite Krystal's own refusal to learn.
* TheScrappy: There have been several.
** Colin (season 2) and Scott (season 6) are both InUniverse for their arrogance and not taking the show seriously, after Scott was expelled, Paul said "Maybe this will wake him the @##! up".
** Donna from Season 4, as a result of her unrepentant attitude toward drink-driving and continuing to believe that she should drive despite numerous health problems. Even the loss of her license she remained as defiant as ever in the e-mail she sent to the show.
** Dale, especially after her antics in ''Ever'', which ultimately resulted in her being expelled in the penultimate episode and made many viewers think she should have still received the title despite being expelled (and she almost did).
** Kevin in season 8 and ''Ever'' was greatly disliked by viewers because [[NeverMyFault blamed everything else on his bad driving]] from the weather to his blind eye, and even swore at Andrew and snapped at him after Andrew stopped the drive when it was becoming too dangerous to continue. Kevin also snapped at some fans on the Show's Facebook page.
** Sly with some fans in ''Ever'', for breaking his distracted driving promise to Aaron from Season 7, and also to fans of Season 7's Shirley, who felt he should have still been named the worst despite his better final drive.
** Sholom in Season 11 is this for most fans. His total oblivious was just painful to watch, and failed all but one challenge. Fans of Jillian were more angry when he was passed over as the worst that season in favor of Jillian
[[folder: Krystal]]
** Krystal in Season 12 was already hated by fans before the first episode even finished. Her driving is scary to the point of putting her nominator (and brother) in harm's way, and she argues that she isn't the worst because she hasn't killed anyone yet. Fans on Facebook say she will either be named the worst this year, or expelled like Colin and Scott.
*** Her attitude once she is in rehab doesn't look any better either, in fact it might be worse. She looks more focused on her phone than the challenges, and even put down Tim's and Phillipe's driving lessons and techniques during the panel section, stating that she "doesn't need to use them" even though those techniques help her to be ''safe''. She also instantly developed a visible resentment and strong dislike of '''Andrew''' for calling her out on her horrendous driving.
*** The pinnacle of her Scrappyness is in Episode 4 where she disregards the "Distracted Driving Challenge" for showing how her texting can be dangerous, and somehow claims to the experts that [[BandWagonTechnique she can text and drive because everyone else is doing it]]. When Andrew and Cam call her out on it, she cusses and flips the bird at Andrew and leaves the room. And yet she isn't [[KarmaHoudini expelled because of it]], although many fans speculate that the most likely reason for not expelling Krystal is that the show does not want to give her the satisfaction of being kicked out of the show. It is later confirmed that at the time Andrew and the CWD panel thought that they still could help her and did not want to seem like they were giving up.
*** Her driving skills and behavior only went FromBadToWorse as Season 12 progressed, and it didn't look pretty. By the time Episode 5 & 6 aired, she is now constantly arguing with her nominator (and brother) Steven, starts refusing to do challenges because she believes that Andrew and Steven is the problem, throwing angry temper outbursts and tantrums and keeps blaming other people for making her feel bad. By Episode 7, her fights with Steven turned physical and she is now being openly hostile to the panel of experts and Andrew himself. Even Andrew asks about the open hostility, and finds out that Krystal thinks that he is the problem.
*** Also, in a terrible record first that could be predicted as early as Episode 1, Krystal managed to upset, anger and piss off the entire CWD panel of experts with her wild and dangerous behaviors, in the order listed below:
*** Andrew, where Krystal constantly attacked him for pointing out (correctly) that her driving is putting others at danger, leading Andrew to state on camera that her drama is tiring him out. His breaking point was when he fustratedly had to state that Krystal's texting and driving habit was endangering the crew and showing that she did not commit to her promises of not texting and driving while moving in Episode 7. The true point however is in the final episode where her many in fractures on the road laws, combined with her road rage text dependent usage, and constant yelling at Andrew, caused him to finally have enough, and call of the road test.
*** Cam, when Krystal breaks so many road rules and laws that he knows are there to keep people safe and she doesn't admit that she is dangerous at all. His breaking point was when she was texting and driving while moving, while the CWD props crew was setting up the slalom challenge in Episode 7.
*** Philipe and Tim, where Krystal defiantly states that she gets bored driving safe, drives dangerously for the funs and laughs, ignoring their driving lessons on purpose because "they are too high a level for me" and brazenly states that she shouldn't need them to help her drive. Tim's breaking point was when he saw Krystal go off road during the trailer challenge in Episode 6, and Philipe's was when she blew off his driving lessons in Episode 3.
*** And lastly, Shyamala when Krystal blames everyone else for making her 'feel bad' and showing incredible anger to the entire panel. Her breaking point came when Krystal stated that she would never understand millennials in Episode 6, despite Shyamala being a ''licensed and practicing psychologist''!.
*** The last episode was possibly the worst of her. She laughed when Daniella was having a hard time on the three in a car challenge, causing everyone to [[DudeNotFunny lash out on her behavior]], and ending with her leaving the car in frustrated denial. This caused her brother to refuse to look at her anymore and [[ScrewThisImOutOfHere disappeared for the rest of the episode]], although the show probably let him walk off the set for his own well being. Then her public road test was considered the worst out of the three, and her constant ignorance, infractures, and yelling at Andrew were too much for him to handle, causing Andrew to end the road test abruptly after she deliberately turn a corner sharp and fast, and him walking off and making his own way back to the rehab center in the camera car. With no needed discussion, the panel names her the worst this year (without the trophy because she didn't earn it), and she ends her tenure as the most hated person on the show.
[[/folder]]
** In terms of most hated nominators; we have Wil (Melissa's nominator) from Season 5 based on his constant yelling that goes into DomesticAbuse territory, and Yolanda (Michael's nominator) from ''Ever'' as she refused to go into the vehicle with him, and even reprimands him if he passes a challenge. Nobody missed Yolanda when her husband (and Michael's original nominator from Season 2) took her place in the second half.
* ShockingElimination: Sometimes, viewers, nominees, and nominators will be surprised over the decision the experts make on who to graduate.
** Bob from Season 1 is the earliest example. Was a road rager who didn't initially take rehab seriously in the beginning, but after talking with Andrew, he managed to control his temper and became the first graduate. Andrew even [[LampshadeHanging notes]] that he thought Bob would be in rehab longer.
** Sean from Season 2. He managed to admit that driving fast wasn't safe, and graduated right after Jodi in the same episode.
*** Early on, Colin's expulsion was this to both the candidates, ''and'' viewers. With his poor attitude to learning, and deliberately failing the challenges, a lot of people expected him to be named Canada's Worst Driver that year. However, Andrew had enough, and destroyed Colin's keys effectively expelling him from rehab.
** Donna's medical expulsion from Season 4 is this. Before the Water Tank Challenge, she was easily the worst driver of the eight, and everyone predicted she would be the recipient of the title. However, she suffered an angina attack during the water tank challenge (a condition she failed to mention to the crew beforehand), which caused the show to remove her from the show out of fear of any worse medical problems.
*** Teagan, at least to the contestant perspective. While Ashley was the better technical driver of the final four and was up on the short list for the fourth time, Teagan was the best out of them in 2 of the three challenges. The three females (Ashley, Amy, and Emily) were not happy about the decision (though Andrew did admit that the decison, regardless of the outcome, would not have produced a good reaction).
*** In any other season, Emily would have been named Canada's Worst Driver based on her lack of skillset. However, she barely managed to leave without the title because Ashley's anger problems kept were seen as more of an impending problem on the road. Also while Emily did get glasses to address here eye sight problems, Ashley never made any attempt to control her road rage problem (especially toward her husband).
** Scott's expulsion from Season 6, especially since it was so quick. After failing the shoulder check challenge, and laughing it off, his nominator Danny had enough and cancelled his insurance effectively tomorrow. Since the rules state that all drivers must have insurance in order to drive the shows vehicles on the courses, Scott was effectively expelled from rehab in the second episode, though based on his poor attitude on learning, he would have been expelled eventually.
** John from Season 7. He graduated from rehab early since he promised to better his attitude after talking with Aaron. The only other person on the shortlist for that episode was Lauri, who despite doing better in the challenges, wanted to stay in rehab for a bit longer.
*** Sly from the same season is this, though not in a good way. Compared to Shirley's challenge record, he failed more than he passed, and looked to be the "winner" of that season. However, he had a flawless road test while Shirley had the worst out of the three, barely saving him from the title.
** Margherita from Season 8. Despite Diane having a better success rate, the experts graduated Margherita on the fact she was able to manage her emotions, fix her pedal control, and being less self centered. Andrew admitted he didn't agree with the decision, but did congratulate her nevertheless.
** Henrietta from the Ever Season. Was disqualified from rehab after admitting she wasn't driving as much anymore, causing the experts to let her go in the first episode.
*** Chris managed to graduate from Episode 1, which normally is the episode where no one graduates. However, he was the best driver of the nine, so they didn't need to keep him on any longer.
*** Dale is another case. Everyone thought she was bound for the final 3 (and possibly "worst ever"), but she left rehab after the slalom challenge, went back home, and broke her hand when trying to break into her own home. With the fact she wouldn't drive soon from that injury, and her complete lack of memory, the experts and Andrew expelled her from rehab. Almost {{subverted}} when she was brought back for the running, but was passed over for Kevin as his public drive was horrific.
** Ian from Season 10. Didn't pass any challenges, but was allowed to graduate early since the experts believe he was the most aware on the personal problems he was making (that and promising to quit as a taxi driver helped his case as well). Even he was surprised on the decision. In most circumstances it would probably have been George who graduated that week, but he had a son who was just learning to drive, and the panel seemed determined not to let him graduate until they knew he wouldn't pass on any bad habits.
*** Tyler from the same season is another case. He didn't pass any challenges in his graduation episode, but his performance wasn't as bad as the other three, and he had more confidence and awareness out of them.
** Tina and Alex are this in Season 11. Both had rage issues on the road, but both of them managed to pass the "Shoulder Check" Challenge, which lead to both of them on the shortlist. When the panel couldn't agree on who to graduate out of the two, Andrew decided to graduate ''both'' of them that episode (though it could have also been that the show had nine contestants instead of the normal eight, so they needed to slim the numbers faster).
*** Jordan. He had a better attitude compared to his ItsAllAboutMe attitude in the beginning, but Renee had a better attitude overall, and was technically better than Jordan. However, when Renee mentioned that she wouldn't drive her son on the highway just yet, the show felt to keep her for one more week and graduated Jordan instead.
*** Both Sholom and Polly are a similar case with Sly above. Near the end of the season, the consensus was that Jillian would be the final graduate, and Sholom/Polly would be the "winner" and "runner up" respectively. However, while both made mistakes on their road test, Jill didn't complete the road test, and the two of them were allowed to leave (they didn't graduate though; Sholom's poor challenge record had him "fail" rehab, while Polly was named the runner up).
* WhatAnIdiot: Two contestants in two separate seasons (same guys under RedemptionRejection) have stated low opinions of police officers, as well as having boasted about very illegal acts (Scott drove under someone else's name while under ''house arrest''). Look at the former occupation of TheBigGuy. He still carries a badge. He has an obligation to report such confessions to the police where these things happen. Yes, he ''will'' fulfill that obligation. Oh, and yes, the judges ''will'' question the intelligence of anyone who boasts about such things on ''live TV''.
** Then-Sergeant Cam Woolley also called Colin from Season Two an idiot, due to his driving.
*** At one point, after deliberately failing a challenge and shattering the car's window in the process, Colin bragged about his actions to a friend. By cell phone. Where at least three other contestants heard him very clearly. Sgt. Woolley was not the only one on that show who considered Colin an idiot.
*** To further about Colin, he went to college for [[HypocriticalHumor police studies]] - i.e. to become a police officer - when he was nominated, and said on camera that he would flash his student ID at any officer that pulled him over and claim he was on his way to an exam. Then, he said he 'didn't think cops were very smart'. Cam Woolley [[TheDogBitesBack took a number of very helpful photos of Colin's car, his license plate number, and the video clip of him saying he thinks police are stupid, and emailed it to all the officers in Colin's town.]] Apparently, he had to sell his car because of all the police attention.
** Many of the contestants have GameShow-grade dim bulb moments when asked to identify road signs. For instance, Dale thought that a sign indicating an information centre (a brown sign with a white question mark) meant that the road to the information centre was shaped like a question mark.
** Angelina from Season 5 is also really bad to the point where she tries a reversing challenge while drinking a coffee without a lid. When she is forced to drop it, she wouldn't shut up about how upset she was. Also, her driving is horrendously bad to the point that her nominee admitted that she tended to crash ''all the time'' and Angelina was convinced that she did well on some challenges where she nearly destroyed them. No wonder she 'won'. Andrew even called her the worst driver of all time.
*** And if you were scheduled to take part in a show called ''Canada's Worst Driver Ever'', what should you ''not'' do the night before you make an hour long drive to the rehab center? Get drunk. Angelina showed up at the starting line with a hangover and had to hitch a ride with Chris.
* TheWoobie: Aaron, considering what he'd gone through. For extra lovability: his positive attitude and insistence on serving as a reminder about the ''real'' point of the show.
--> "Aaron, buddy? Everybody loves you."
---> Andrew Younghusband, during a "You Asked" preseason episode.
** To a lesser extent, Melissa from Season 5. The Rolls Royce was also one.
** Season 12's Mike is one, considering his tragic backstory.
