* NightmareFuel: The [=VINs=] are surprisingly creepy, being mass-produced identical white robot cars who have barcodes printed on their sides, {{Machine Monotone}}s, and no personality of their own. The cutscene in which they're introduced reveals - [[SurprisinglyCreepyMoment complete with ominous-sounding mechanical music]] - that they are actually Chick's students, who all went through a giant factory to become [=VINs=], [[CyberneticsEatYourSoul losing their personalities and identities]] in the process. By the end of the game, they have replaced Chick's students altogether - with one race even having Lightning race against only [=VINs=] - and it's never revealed what [[WhatHappenedToTheMouse happened to them by the end of the game]].
* SugarWiki/NoProblemWithLicensedGames: ''Race-O-Rama'' is widely considered the best ''Cars'' game for how it evolves the gameplay of its predecessors.
* ThatOneLevel: The Guido Kart Races are the most difficult game modes compared to others. The controls are very finicky, and Guido frequently spins out if he so much as scrapes a wall. There's even a [[ThatOneAchievement achievement/trophy]] named "Crowd Karter" which you must place 3rd or better in Guido Kart Races.
