In some respects you are right MrLapou. We complain about speed cameras being here there and everywhere, but driving the 100 miles from Swindon to my home yesterday along the A361 and A422, I think I came across perhaps 3 or 4 cameras. That gave me ample opportunity to drive like a complete loon, even in locations that were clearly dangerous if I wanted to. If I get caught, it's my ****** fault, as most cameras stick out like a saw thumb.
However, the point is that many cameras are in locations of no benefit, other than the financial one. And where there should be cameras there are often none.
But what about our extremely shoddy road markings and signs? Every couple of miles I see blind corners with a broken centre dividing line, or turnings and cross roads with little warning. Why doesn't the UK use overtaking signs, like the rest of the world? If you are stuck behind a lorry on an A road, what are you going to see first - the no overtaking centre line or the sign? Or how about the crappy A road driving of most people in this country? Tailgaiting each other so no one has a chance to over take, unless they push in - and of course then they complain. Or how about people (especially lorry drivers it seems) who refuse to use their full beam at night so you have no idea that a overtaking opportunity is coming up.
I think there is a lot more that can be done in addition to the appropriate use of the safety camera 'miracle cure'. In cities, however, I'd stick a camera every 100 yards and reduce speed limits within cities to 30mph everywhere, and 20mph off main roads. That's were people's lives are at risk. Everywhere else, it is mostly the driver putting their own life at risk.
