What's The Best Smartphone Car Game?

Smartphones aren't just handy portable porn-viewing devices. You can play stupid games on them, too! Some games even have cars in them.

My buddy Tirey at Evil Genius Racing just turned me on to Hill Climb Racing (for iPhone and for Android) and I've been stuck playing it ever since. You need two hands, so I can't play it ont he subway, but other than that it's simple and addictive.

Do you know a smartphone car game that's better?
