I think this has the potential to become a really fun racing game. One suggestion would be to tone down some of the visual effects, as they can make it a bit harder to see what's going on. I'd also make the car start off a little slower and gradually build up speed, which would make it easier to control and give the acceleration a more satisfying feel.
Overall, I think it's a promising project, and I hope you keep working on it. Great job!
