right firstly its illegal to slam on the brakes and give em a fright...

secondly i am a BMW driver and a ford etc etc.....my dad told me something one day that really hit home, i was bitching about someone doing the3 same thing to me, sitting on my arse and generaly annoying me, he said why didnt you just slow down and let him overtake, told him i thought he was a prick etc.....fk em, dad said "if it was me behind you and i was trying to get to you or christopher (his grandson) maybe you had been hurt, taken to hospital etc and you did that to me i would ram you off the road becasue no little smart arse is going to stop me gettting to you if you were hurt........kinda hit home.......i think i would go crazy if i was desperatly trying to get somewhere.....its obviously not going to happen to everyone and 99.9999% of the times its going to be a prick behind you but what happens if you are holding someone up from getting to their loved ones.......

think about it!
