Probably true, but it's not going to happen without a huge amount of additional surveillance. I'm a daily rider and in all honesty I ignore speed limits when I'm away from habitation. Nothing crazy, but definitely illegal. For the most part I'm pretty responsible, and keep to well within limits around where people live. But there's no denying that speed is part of the appeal - I whizz past all cars (because I prefer to be away from them), zip around bendy country roads (because it's fun). I don't even have a fast bike, and I find it hard to stay within limits. I'm in my 50's and have only had one accident - an off-road mud-slip in the middle of nowhere resulting in a broken ankle .. and a long walk.
At least with motorcyclists its their own lives, not others like when car drivers speed excessively.
