Some folk ride very high horses
Often as a result of bitter experiences, such as the loss of loved ones in car accidents...
Re your signature - its not speed that kills - its the misuse of speed that is dangerous. I have driven high performance cars both on the road and on the race track at high speeds (remember when there was no speed limit in the uk?) safely. It can be lethal to drive at 30mph in the wrong conditions!
Agree for the most - but ultimately when you crash, the severity, injuries and likelyhood of death all increase when the speed of impact is increased. Therefore, speed kills 
Why crash - inappropriate use of speed with regards to road conditions maybe?
High speed impacts - Top Gears "hamster" survived. I also know a guy who barrel rolled some years back at the Pod at in excess of 180mph - broke a lot of bones but survived.
I don't condone misuse of speed on either the roads or the race track - agree the harder the impact the bigger the risk of injury or worse - but ultimatelt it in not speed per se that kills. I have seen people killed in relatively low speed impacts.
I think i will agree to disagree with your view.
[edit]Reference Entwoods comments about racing at 120mph on the roads - couldn't agree more - that is moronic and stupid. Racing should be undertaken by sane individuals on a race track.
By the way referring to the lack of uk speed limits was not meant as a "comparison", rather to demonstrate that one could drive at high speeds in the right conditions legally then.[/edit]
