I'm not a total speed nut actually. I think that there should be more use of variable speed limits and associated driver guidance and education, now we have the technology. Weather and visibility are really important factors in driving, for example, and people are generally reluctant to slow down sufficiently. Similarly many people drive too close to the car in front, for some reason I can't fathom, which is also a very bad idea.
I would put more traffic police out there to stop and explain to drivers exactly what they are doing wrong in the case of minor offences, which concentrates the mind a lot more than being fined IMO. They should also put speed limit signs on safety cameras so there was no doubt for drivers - believe it or not, most drivers don't actually want to knock people over and understand cameras are used in accident blackspot areas (although when I looked into the relationship between accidents and cameras in our area, sometimes they had been put up in response to relatively minor incidents on busy roads whereas there is one place locally with a badly designed crossing where there were two extremely nasty accidents in as many years, including a fatality, but on a road with less traffic, and this has not had a camera installed, which leads me to think there is a link with possible revenue here).
My view is that if you have had to issue a ticket, then something policy wise or transport planning wise has failed, particularly if more and more tickets are being issued over the years, which would suggest drivers are getting 'worse' or less compliant rather than better.
I got my one and only speeding ticket in 20 years simply because a speed limit was arbitrarily changed in the middle of a long road at the geographical location of a county boundary, which was a political reason for the speed limit change, rather than a safety-based one in my view. This just makes a mockery of the system and I was not impressed once I worked out what had happened. I had allegedly been doing 37 mph in what used to be a 40mph zone until a few weeks before, which isn't so extreme. Interestingly there were also two cars on the picture when I looked, and it wasn't even clear I was the one who had been doing 37mph at the time, but I was advised by the solicitor it would cost me £2000 to contest the ticket. Now what sane person is going to bother standing up for him/herself in such instances? So it was easier to pay the fine and just be cross about it. BTW in my area they don't do driver awareness courses either, which I thought was a bit unfair.
In summary, I think it is all too easy to bully relatively safe drivers for odd minor offences, whilst missing the bigger picture sometimes.
