My favorite getaway trick requires a small, flat as possible vehicle. Good example is the Stinger. Well whatcha do is drive towards ammunation stairs at a speed they can keep up with. Then you drive up the stairs and they quickly pursue, as they have to if they are to make the roof. Then, you slam on the brakes and stop at the top of the stairs. Watch the car sail and then tumble like a tumbleweed and usually burst into flames, as you back down the stairs and speed off in the other direction.
