I wish the police could use the PIT manuver to spin your car and the spike tacks would be automatic.
And about that cruise idea I want to add some thing. You can cruise the climb into your back seat and shoot the cops behind from your back window. But jumping out of your vehicle wouldnt work. The game is too smart that the cops will follow you because it know that you jump out of your car so that means computers are dumber than human.
I also wish like the car is like James Bond; can shoot out missiles out from the back and front, mines, machiene guns, automatic coffee maker ( ) spikes, and many more
Most of the surroundings must be destructable, like a wodden cabin can be set on fire, Walls can be broken into with a car, so it would be more realistic.
