Avoid being shot
When your going to the docks, or when your going up street one, you'll encounter buildings with massive armaments atop them, this is possible to jump out and simply dodge them, but that is luck and it wont always work, so when you get near guns, spin the car around so the driver isn't facing the guns and pop out (Select). Then use your car as a barracade, you can shoot out but they can't shoot in.
