You really have to try this one. It's a superb project both technically and conceptually.
DDB Paris and 
Unit9 brought together Google Maps, flash and Facebook in order create an incredible real time multiplayer racing game where you can customize the Mini of your choice and race wherever you want with friends or foes.
Play: 
MINI MAPS
I had a problem running the game on Firefox but on Google Chrome runs smoothly.
