Well Bob, I did say I was'nt condoning it. But here is an example. The A46 from J18 M4 down to Batheaston bypass. Lots of swoopy bends and shortish straighter sections. Used to be a mix of dotted white lines and solid. Now its all solid, because of accidents involving cars, vans, lorries etc. But in the parts where there used to be dotted white lines, a bike like a Blackbird could easily be passed in a fraction of a second. Cars cant do it, and the accident rate proved it, but a bike could.
Yes, I agree, its best to have a common policy, its just that most policy is decided with 4 wheeled vehicles in mind. And, a friend of mine got killed (in his car) by someone else coming round the wrong side of the road where it was still a broken line. So lines are not necessarily a guarantee of safety, because people break rules whenever they see fit, for whatever reason.
