Grand Prix 4... Game may be from the 2001 F1 season but is easy to mod with various car sets and update to the latest season.
Pure... Off-Road ATV game combining Racing and Stunts, Not a bad game.
Moto GP08 & Superbike 08.. Two of the best Motorbike racing games out there.
Trackmania series.. Extremely addictive games, and a vast online community.

Cheating German? where? All I see is the car of an at the time two time champion.   Next year it'll be a red car.

P.S.. The car that finished the year as a two time champ to be more accurate LOL

Adelaide = Damons own fault no real intention of a collision had he not been in a hurry to get through then he'd be world champ

Jerez = No argument there even Michael admits it, But then again only a few years earlier the almighty senna didn't bother waiting to the near end of the race, he just speared Prost right off the track first corner for the title. (Ooops how dare I speak bad of the almighty )

Monaco = Stupidity but got punished and gave us the great fight through the field.
****

*** All tongue in cheek for those who take it seriously. 

to borrow a quote.. "7 times world champion, the rest is just a matter of opinion"

for the sake of fairness, i must point out Test Drive: Unlimited

good graphics, and realistic enough to feel like you're really driving, given you get the appropriate gear to play it on (read Logitech g25) or, go the insane fool way, and build it yourself, like me
