i think you've said everything i was thinking , i also ride with full beam when filtering.
it's clear that a huge number of car drivers do not use there mirrors how many times do you sit behind a car and you can't see there eye's/face in any of the mirrors. how can they see behind them then?
how many time's have you seen a police car behind a car in the outside lane horn's and light's and the car doesn't move because they are in there own little world.
matt ride abike you will have a totally different perspective on car drivers i only passed my test 3 years ago never riden a bike before that it's totally changed the why i drive..
cbt should be compulsary when taking car test it would grately improve the safety on road's
