Just get the number plate, rule one.
HEs gone then.

My misses before we went out got hasseled up in the belgrave hills on her way to work. Around where puffing billy goes along here in Vic.
this prick tailgated her through the hills so she pulled over and let him go.
HE started the stop start routine in front of her old holden station wagon ,an old HQ wag.this went for miles.
He was in a hotted up valiant pacer, dice on the mirror etc..
She just put her foot down and pushed him along from behind and ran him off the road he stopped, she went flying past. next town he comes around a round about the wrong way and stops her takes her keys out of her car. She goes to his car takes his keys out of his .they are running around swearing at each other.
This fool calls the cops and they turn up at my misses work with him cause he wants his dents fixed. The stories are told and this fool says in front of witnesses that he hates surfrs and surfy wagons anyway!
My mises said the joke on you fool we are 40 miles inland I dont surf its just a fukin car.
The cop let it all go, seeing 'she' didnt want to press charges if he dropped his of ramming.
That was 20 years ago there are worse people around now, best avoid them completly or say sorry before you swear at them.Put them at a false ease promise them anything,Walk away safe ,note their number plates down and get some cops you know personally to put a pollution exaust immitting roadworthy style check on them for the next few years.
They have to take their car to get it checked at their expence then go back to the exact cops and its up to them if they let it through or not.Which they do , then they pull them over again and again till they get the message they have fucked up royally and change cars.
