We need to look back at the real cause of the accidents. It is **NOT** always speed !
It is either people not paying attention or making stupid mistakes out of frustration.
WHY ? Dawdlers. The 'I must be a good driver cos I'm doing 22 mph in a 30 mph limit' idiots that hold up lots of people who all have places to be at prescribed times. There was a time when dawdling was actually an offence. Now everyone wants us to dawdle. So those of us that have to get somewhere get up and set off several hours early just to allow for these people. We are all tired and frustrated by this - in some circumstances this leads to mistakes. If the dawdlers were not there, this would not happen. Ergo : make dawdlers retake their driving test, but make it much more stringent. If these people cannot drive at the speed limit or as conditions dictate - eg. rain, ice, etc. then they should not be driving.
Now on to my next pet hate : the 'speed indicators' that warn you when you exceed the speed limit. Except some retard has set them for 0.000000000000001 mph above the speed limit, so even correct speed traffic gets flashed. If I am doing about the speed limit, and I am paying attention to the hazards on the road ahead then I am a far safer driver than the dawdling twit '22 mph - must be a good driver' halfwit with his/her nose glued to the speedometer. I will be far less likely to crash as I will see approaching hazards. The halfwit on the speedo will just end up with it embedded in their skull when they crash as they are not looking where they are going. And I have to pay taxes for their treatment. What is the point of these stupid devices except to boost my ego as I exceed the speed limit on my push bike (not for long - pant) ?
Now my last pet hate : the scum that use their mobiles while driving. I have to thank all of you idiots at least in part for the current state of affairs. You weren't paying attention when you had that accident were you ? No you were too busy pissing about texting a mate. Except you couldn't admit that could you ? So now thanks to your part to play in this sorry tale we all have to suffer. A lot of you are still doing it now. If you're in an accident with a mobile using driver, I suggest you insert it as a suppository in that driver. Shame mobiles have shrunk since the 80s ...
What is needed is a common sense approach. I am sorry for any family that has lost loved ones in accidents. I truly am. But as I describe above, speed in most cases is not really the problem. Blatant speeding is, but speed cameras will never stop that, and it is only a *VERY* small part of the issue.
What we need to do is get people paying attention behind the wheel again, and driving at a speed suitable for the conditions. So as far as speeding is concerned, about the speed limit give or take as long as you're paying attention to hazards is OK. Hmmmmm a bit like the olden days when the rozzers followed you for a bit to make sure you **really** were paying attention. What we really need is a zero tolerance attitude to not paying attention while driving.
