someone should make one.... that would be awesome. Cross country, any car, any mods. Maybe a budget, stopping for hotels and gas etc. I think it would be sweet. That's just me though...
I think this is a good idea. If only I had the time and a staff of artists, I could code this for the PC. I think it might be relatively difficult to get access to the PS3 dev kit, I could probably buy in to the XBox dev kit though. Lots of co-marketing opportunities with this concept. And sequels. US, Europe, Africa, Middle East, Asia... Hmmmm.
There was one made for PS2 a while ago...only released in Europe though. North America has yet to see a Gumball 3000 game.
