What an eye opening thread! I think I'll sell my road bikes! What bikers fail to realise is how completely selfish their behaviour is.
I went on a cycle tour with my son (on a tag-a-long) this weekend and the road we were planning to use was closed. The only alternative was to do few miles on an A road race track! Bikes (and cars) were travelling way in excess of the speed limit. I genuinely feared for our lives!
Also the parallels drawn to MTB earlier in this thread are meaningless; if I go beyond my limits on the MTB the only person that gets hurt is ME!
