Nice game, I like the idea.. I think is the first car game that I saw in this JAM. I miss the sound of the cars during play and also when you turn on curves it doesn't slide very well. Also some background music can give more atmosphere.
On the picture below I got stuck in a curve .. maybe in these cases you can show to the users "game over" or put the car back to the trace.
Good Job.
My game is a casual game if you wanna rate is https://misterm.itch.io/mixtape-match , Thanks
