One of the most braindead games in existence. You have to play for hours to unlock the speed classes that can even be remotely considered not slow, there is basically no challenge during the first 99% of the game (you will invariably pass every AI even by driving slowly), the same courses are repeated over and over, and the game has near zero depth since you refill nitros at the same rate no matter what you do and it doesn't even really matter when you decide to use the nitros because drifting allows you to bypass any corner in the game. I imagine that this game gets mentioned only by people who aren't serious about racers to begin with or just really suck at them, and even they probably never actually finished this.
