A good looking, good feeling game, with a lot of funny meta humor! (I defnitly had to laugh a few times!).
I feel like you are relatively safe in the middle of the road? It's weird because it doesn't look like it in your screenshots, but I could just stand in the middle of the street for minutes without getting hit. Maybe this could be fixed if the other cars had more movement options (maybe you'll encounter another crazy ghost driver, just like yourself). But of course I understand that time is always a limiting factor in a game jam!
One very minor issue I had was that the Z-odering sometimes didn't work properly (oddly enough, it seems to be right after the introduction of the cones, but before that, my car was sometimes behind other cars when I was supposed to be in front)
Other than that the game is definitely fun, well made and worth a try. I also found the music quite fitting.
Good job!
