Why do you use high beam whilst filtering? Do you think there is more chance of being seen?

It's a fact that when you ride on high beam, motorists cannot judge how far away you are. So whilst you are pootling down on high beam, the car driver has a split second to make a judgement whether to dash for that gap in the other lane...kerblam. I think you'd be seriously lucky to get 100% in your favour if it went to court too.
