Probably sometime in the future you would be practicing NFS on your iPhone, before actually given a test for a drivers license. iDriver on the iPhone takes things much further than what Viper smart start demonstrated recently. Here, you can use the iPhone to drive an actual car, using the accelerometer to steer, and the buttons onscreen to brake and accelerate. WOW! Video downstairs.
