This is like the ad where they show you hitting something at the higher speed and just missing it if you had been 10km/h slower.
What about if you had been paying attention at 130km/h and not paying attention at 90km/h? How much delay in your reaction time would it take to make these stopping distances equal?
That's the straw man argument Sotired.
But anyway.
You'd have to be asleep at the wheel for an extra 2 seconds, The stopping distance at 130 kph is 120 metres, at 90 kph it's 64 metres. To waste 56 metres at 90 kph, 25 metres per second, that's 2 seconds.
If you're asleep for 2 seconds you've hopefully already run off the road, coming to rest safely in a ditch, before you hit anything.
Alertness is a factor but unfortunately you can't police it. Just because you can't police one factor doesn't mean you should throw your hands up on the ones that can be policed.
Well, its a pretty strange argument anyway. How often is it that one is presented with a completely stationary object in the middle of the road where you have just noticed it and have to stop completely before hitting something, from your normal driving speed?
The only scenario I can think of is where you come around a tight blind corner and there is a cement truck or similar stopped in the middle. I can't say that this would be a highly rated cause of accidents on the roads. If you aren't already hovering over the brake as you go around that corner, you are going to hit that object anyway.
Instead, I suspect that in the majority of cases accidents are caused by people doing dumb things. It just so happens that catching people speeding is easy to do, and much easier to police. I do believe there is a link between the people doing dumb things and the same people speeding in stupid locations, so I actually don't mind that speed cameras are used. After all if you are not observant enough to know there is a speed camera in a particular place, or that traffic conditions warrant you slowing down, maybe you deserve to be fined.
The police comment that seems to appear in accident reports of 'speed was a factor' is disingenuous in that it only means 'if they weren't moving they wouldn't have hit anything'. They never actually say that the cause of the accident is that the person is speeding, only that maybe if they weren't speeding they might not have driven into a tree.
I recall driving home from the snow one Sunday evening and watching some twit overtake people on the wrong side of the road on a blind corner, going up hill. Technically he probably wasn't speeding, but he was being an idiot and risking his life and everyone's around him. Unfortunately the only thing that seems to prevent that behavior is obvious policing, i.e. having a police car or two cruising in the line-up, but I guess that is more expensive than just having cameras.
