The eyewitness account of that accident actually made me go cold reading it. That poor guy. Completely horrific.

Completely agree with AndyK, good comment.
The problem is that Bradley Wiggns will be listened to on this because right now he is so high-profile. If he is going to call for anything it should be much harsher penalties for dangerous drivers, enforcement of existing driving laws and a blanket ban on driving able-bodied kids to school. Get people off the road who can't be trusted behind the wheel of a car, and not for six months or three points - for a long time. No special pleading that they need a car to be able to live - no, you don't.
A helmet would not make my commute any safer, the thing that would do that would be a higher standard of driving - stop turning aorund to yell at your kids, look where you're going, drive slower, get off the phone, and generally just concentrate on what are doing and where you are aiming your tonne of metal.
