PS: If you instantly crash at 70mph or more you would instantly die from internal organ damage as you stop but they all keep accelerating towards the front of your body and get in effect liquidised...Worth keeping in mind next time you decide to nail it up a piece of road.
Can you elaborate on "instantly crash" at all? I've crashed travelling in excess of 70mph a number of times on road and racetrack and as far as I can tell I'm still alive. Sure, if one hits an immovable object such as a tree, truck, or a wall at 30mph then the likelihood of surviving isn't great, but riding bikes and staying alive is all about managing risks. Weigh up the potential consequences and act accordingly.

I'm not advocating that everyone rides their bikes flat-out whenever they can, but that the judicial system keep things in perspective... You ride your bikes how you prefer to and I'll ride mine the way I like to, that way we can all be happy
