I don’t believe going slower will cause accidents or put people at greater risk, any more than I believe going faster will in the right situation, but a balance has to be struck. (That word again). If traffic is slowed down to a point where pedestrians are highly unlikely to be killed in any collision, it starts to negate the whole point of using a car.
Something I noticed when I was in France recently was that the traffic seemed quite manic, in Monaco for instance, but pedestrians just seemed more road savvy. There is absolutely no doubt in my mind this is certainly, in part at least, what we have lost in this country! The onus of pedestrian safety has been totally foisted upon drivers, and woe betides anyone who dare suggest maybe pedestrians should address their own bad habits. The approach should be holistic yet the focus is always on car drivers and speed.
I was shocked to hear George Monbiot on Radio 2, quite some time ago now, talking on the effects of lead poisoning verses crime. (Bear with me). He said he’d completely changed his mind on this possibility in light of new evidence of a 20 year delayed effect on crimes after lead has been eliminated from petrol, paint and water pipes etc. The effect and evidence holds true in America and European countries from different decades when the widespread use of lead was stopped. Now I’m no fan of his, for his denunciation of someone on a different topic,

but I have to say it was quite compelling and I’ll get to my point now..
What interested me most was a phrase he used and how I think it relates to speeding and road safety, when he said there’s a big difference between “Commonality verses Causality”. He went on to define the important difference between the two meanings, which is not difficult to understand of course but yet escapes the minds of these road policy makers and enforcers. If accidents go up or down with a corresponding increase or decrease in speed the most important fact and information you must find out is whether it is either as a direct cause of some change or simply a commonality, as Monbiot said in his example on the radio. The importance of this cannot be overstated; it is the difference between getting at the truth and a complete red herring.
