OK, I've played the game.
It's actually quite a bit of fun, well done!
One more idea - figure out a way to make moving the car take points away, points which perhaps accumulate at a regular rate, but if you do too much moving the car out of the way, you run out of the ability to do, and risk getting hit. This would encourage advanced planning.
You'd need some kind of gas guage.
You could also allow a certain number of collisions - maybe the car could change through few different configurations of the LEDs that comprise it, like it shows it getting damaged until three strikes and you are out.
Added: there is no winning - I'd like to be able to reach the end and drive right off the track and get a reward.
