Absolutely.
Before speed cameras came in I believe this was the Police message to the government. ie camera's won't help much we need to re-educate drivers and improve the standard of the average driver.
The government, it seems, wanted to be seen to be doing something so went the easy camera route.
I think the whole thing came on the back of a massive Police survey of accidents. They recorded the reasons for all accidents over a long period of time. The results got reinterpreted to put speed at the top of the reasons chart - when it was lack of driver skill and awareness that they scored highest by quite a margin I believe.
iirc the one they jumped on was 'excessive speed for the situation', which of course isn't really the same as speeding and I believe the police initially pointed that out.
anyway!
I prefer trundling along green lanes these days - and my 90 is most comfortable at 50. 60 if I rev it a bit harder but still value my hearing in the long term. 65/70 only comes on a motorway with a big down hill.
