Can you please add a "parking simulator" mode? Iam not joking, my SO wants a simple way to train parking and I think that could work very well. Or maybe just let one draw obstacles.
It's probably not a realistic enough simulation to be a viable learning aid, but that's a funny idea.
I might build something else on top of this though, and will try to keep parking in mind!
There are various games that do this pretty well. For example: https://store.steampowered.com/app/4265570/Parking_in_Tight_...
