re: 4wd - time to bad them in the city well mate you better ban all the cheap tin boxes, any car made prior to 2000 and basicially just any car on the road.
better still any moving object in control by a human should be banned
eliminate cars busses planes trains and in fact any of newtons laws.
indeed everything should just not move because if your the size of an ant stiff f#ckin sh!t.
