what happens when cops with radar gun found you're speeding?
do they jump out in front of ya car to stop ya?
do they chase after you in their bike/cars?
or do they write down ya number plate and send you a fine later?

i see cops using radar guns on freeway north and graham farmer,
its possible for them to jump out in front of ya car and stop you
and i dun think its that easy to just hop back in the car and still be able to chase and stop you
and its not all that easy to record number plate on a fast moving car.

if thats the case, why do they even bother to use radar gun on freeway?
