It's a tragic irony that a cyclist has been killed by an Olympic bus in London the day Team GB won its first Olympic Gold cycling medal. I know Britain's new hero Bradley Wiggins (left) thinks helmets should be made compulsory (though I see that as a headline not as a direct quote from him yet). I'd say a more effective change would be to copy the Netherlands and Norway (and other countries I'm sure) where the driver is automatically held legally responsible after any cyclist/vehicle collision. In the UK the solution is always that every other user must "armour up" against cars. I'll grant you the stamp pic of Bradley shows him in a helmet – ditto all the riders in the Tour de France I think who were hurtling through crowded lanes at speed. I'd wear one in those conditions too. I know this is an endless debate – my husband Chris wears a helmet everywhere and I don't – but if you wouldn't relish the prospect of wearing a helmet in a car to reduce the risk of head injuries you'll know in a nutshell why some folk don't want to wear them all the time on bikes.
