Just a note on cameras over here.
Regarding static roadside cameras or gatsos I've been flashed 3 times over the last 3 years by these followed by the usual letter ostensibly 'fining' me £60 and handing me 3 points.
I've basically given them the finger each time and nothing, bar 1 or 2 more letters 'reminding' me with veiled threats, has ever, ever happened. The first of the three was in July 2007

and most recent November 2009. Make of this what you will but I honestly think most of these 'crimes' are invalid for some reason so they never pursue them past the cursory letters (faulty gatsos maybe?).
I simply completely ignore them and they seemingly forget about it/write it off.
Similarly with seatbelt offences. Done twice in last 12 months (February and April) and just ignored them. Eventually I got a bailiffs letter and that was 6+ weeks ago, like they're going to bother with a £90 job (bailiffs are another story obviously but they're fairly easy to deal with too as they simply have no powers if you take the right steps).
I hope I'm not coming across badly here but I totally resent the camera

fine culture in this country, nothing more than a stealth tax imo.
I'm an excellent driver and have only been guilty of fairly marginal offences. One of the seatbelt jobs was a sting with the cops waiting around a corner for people, disgusting. I told him I had no intention of paying and he started making grave threats regarding imprisonment etc. I just laughed in his face and that was back in February.
Each to their own of course but having been done 3 times by gatsos and twice for seatbelts in 3+ years with the last one 6 months ago it's cost me the grand total of..............
£0.00Obviously I wouldn't advocate my approach as regards abroad given what I've read but this is what I've experienced in GB.
