[Biker Biggles]

I think that while making car drivers take a bike test might make them better car drivers it aint gonna happen.Also,this line of thought tends to distract bikers from a simple truth,and that is we are responsible for ourselves out on the road,and it is dangerous for us to expect or rely on car drivers or anyone else to keep us alive.Far safer to believe that all other road users are totally inept and ride accordingly.
Having said that,I think as bikers we can improve our own skills and abilities by driving cars.Having a car drivers perspective on a situation can assist us to anticipate what a car might do and ride with that in mind.The classic accident which springs to mind is the filtering one where a car turns right without checking in the mirror.We may have established legally that the bike is often not at fault here,but prevention is better than cure.From a car drivers pov,you want to look at what is coming towards you when turning across a road,and it takes a real effort to think about looking in the mirror for filtering bikes(even though you should do).Worth bearing that in mind if you are the filtering bike.
