My wife attended one of these and said it was very usefull. I have a sat nav that pulls these things up and continuously "bongs" me if I am going too fast. Don't know how it does it but it works. Good to see one of the respondants has such a tame view of life and has never done anything wrong
it could be that if we all drove at the correct speed and all kept the exact safe distance appart WE WOULD NEVER GET TO WHERE WE ARE GOING FOR THE QUE! 
Hey if you are refering to me, I have reached the grand old age of 43 by luck. I am no angel, have had a run in with the legal system when I was younger. Crashed my own motorbike twice. You do reach a certain age and realise "hey I could die doing this"
In my youth I lost 3 friends in motorbike accidents, 1 friend who flipped a hillman avenger, and witnessed loads of idiots roll a vw camper van.
Call me boring if you wish, but I now cling on to life with a vengeance.
It is now my goal in life to be the oldest person in the world, and really hope I can be immortal, to be old git that moans about young people all the time

Apolgies, started to rant again, must control myself.
I was a great supporter of speed cameras for a while, but I changed my mind when I saw some of the places they are installed, and when the government released figures on how much money they earnt of them.
By the way I was caught by PC holding the speed gun.
Felt sorry for him really, he looked really pleased when he flagged me down, then really nervous when he saw me, 6 foot 4 and quite a big chap. But really a gentle giant type. I was nice as pie and fully admitted I was speeding, as I new I was.
