Anyone know of any Massively Multiplayer Online car racing game?

I am looking for something that allows me to jump into a car and race with other online gamers?Anyone know of any Massively Multiplayer Online car racing game?
Even better than that, try getting a drivers license, and a car, and jump into it and drive up I-5 during rush hour.
Multi Theft Auto is a great online mod for the GTA series. I just started playing MTA: San Andreas and had played MTA: Vice City before it. Highly recommend it, it's GTA!



Also I'd recommend the Need for Speed game series online (Underground/Underground 2/Most Wanted), fun game to play online, even with the demo.Anyone know of any Massively Multiplayer Online car racing game?
You might try Auto Assault.
Try Forza:Motorsport. That is by far the best car racing game. In addition to that-it's the most realistic. It is on the Xbox.

It has amazingly detailed graphics and some cool features. Such as putting custom paintjobs on your vehicle. No, not like in Midnight Club and alot of other games that give you preset paintjobs, you can create your own. I've seen Batman cars, Superman cars, even Spongebob.

If you have ever played any of the Gran Turismo series, it's alot like that, but much, much better.Anyone know of any Massively Multiplayer Online car racing game?
For a computer or a console? Also, what do you mean my massive.. like 6 or more? I like Burnout Revenge for the XBOX 360 and not for the XBOX... there are different types of racing and it's really fun.. although I prefer Burnout 3.
