These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Critical Dissonance: Most critics disliked Driver 2 and preferred the original, chiefly for the inclusion of what was seen as clunky on-foot controls, while the majority of the Driver fandom considers it an Even Better Sequel.
Ensemble Darkhorse: Tobias Jones, to the point that he was brought back in Driv3r after he apparently died in Driver 2.
Good Bad Bugs: Driv3r is general is pretty buggy, but in the PS2 version, there's a huge glitch you can do in Nice. Go down to the airport, and slowly drive over to the bush you see on your left. Doing so will cause you to fall through the ground onto a piece of land below. If you go in with a truck, and drive off said piece of land, you can launch your self out of the glitched area and into the sky. This is sadly fixed in the Xbox version.
Scrappy Level: Arguably, the very first mission in the series, where you have to do a list of stunts to prove yourself worthy of continuing. Said level takes place in a tiny underground garage, you have a minute in which to do the stunts, and you can only hit any obstacle three times (though much of its difficulty comes from younger players not knowing what a slalom is). This level is remade in an unlockable challenge in Driver: San Francisco as a Nostalgia Level. Thankfully, not mandatory.
Another major problem with the driver's test is that it's effectively a tutorial level in which you have to perform all these basic skills, but the game doesn't tell you how to do them. Not to mention how finicky it can be in certain segments, like what exact route you have to take to pass the slalom part.
The motorcycle chase in Driv3r is infamous for being insanely difficult and unforgiving; in order to keep up with Calita, you can't screw up even once or you're pretty much guaranteed to fail. There's a chance you can crash into her at a certain point and end the mission early, but you have to be quick about it.
Chase the Gunman from Driver 2 is known as one of the most difficult missions in the series by many, if not the most difficult. In it you have to destroy a red car on a narrow mountain-side road with lots of traffic. If you crash into anything at all, you might as well restart the mission as you have very little chance of catching up to the red car.
Rite of Passage from the first game, which involves driving from Brooklyn to the Upper West Side of Manhattan under a strict time limit in the rain. You need to be absolutely perfect, and the invincibility cheat doesn't help because you're more likely to fail due to skidding in the rain or just running out of time trying to make it. Luckily, if you take the second choice for the first New York mission, you skip Rite of Passage in exchange for a much easier level.
So Okay, It's Average: Parallel Lines got this reception from critics and fans. While it certainly got right a lot of the stuff Driv3r got wrong, it's still regarded as a rather average GTA clone.
