I think there should be new car physics, for example, bumping into the back of a car in order to slow it down or make the condition worse.
I also think that police should be able to arrest criminals better because its much harder to arrest criminals (going into the car and putting you camera at a angle to see the inmate in order to cuff it and arrest it, also causing a character sliding glitch) Possibly clicking on the car with your cuffs in order to throw the inmate out of the car to arrest it.
