interestingly enough i have recently joined some biker forums and i am hoping to get someone to put me on a bike so i can learn how to make their lives easier on the road
in slow moving traffic i try to help them pass safely by moving over a bit. let them get on with it. i gain nothing from holding a bike up behind me so i would rather see them pass safely and get on their way. they should however be passing at a responsible speed though, not too fast!
in normal paced or fast traffic they should overtake properly though ie using the next lane to overtake.
conversely if its single lane they are going to pass me if they want to so i try to help them by riding the nearside line and giving them a left wink when its clear to overtake.
generally speaking i like bikers and i regard them as having better skills than the average car driver (i do recognise that most people here are better than average car drivers and i also recognise that some bikers let the others down just the same as truckers etc. we all have our black sheep. except car drivers who are mostly black sheep and have the less common white sheep
)
