Use arrow keys - Up to accelerate, down to brake, left/right to steer. Mouse for handbrake.
The original game is "Racing Game" by howardabrams. Used under the Creative-Commons Share-alike 3.0 license. I added a velocity system and realistic steering/drifts. I also made it so that the ai car now has dynamic ai. I made it so that you have to press the up arrow to speed up. I made the cars smaller so that they are harder to crash.
