I could say that one problem would be that when you try to stop it, it should stop almost instantly, but when you try to stop the car it continues a little longer until it stops.
I know that it will not be that fast in the real game but maybe lower the steering sensitivity
Ever tried breaking in a car irl? The one in the game is pretty accurate. Accel is too fast though
I am making handbrake for that and I made the car speed fast because I was trying to make my car-free and easy to move as I am going to make driving simulator I will decrease the speed of the car as per the need
