good overall, but room for improvement
One thing I noticed was that all the other racers all went in the same line. And that AI seemed to not ever want to deviate from that line, even if it meant hitting objects. Also I've noticed that it will often end the race a lap early, so you should definitely fix that. Otherwise good except for the fact that your car almost completely stops if you get bumped in any direction. I know it might be slightly more realistic this way, but it would be more fun like bumper cars you know?
don't get me wrong though. I really like it and have been playing it a lot.
