There is no doubting that a minority of cyclists behave irresponsibly on our roads. But that is true of road users of all modes of transport, including motorcyclists. I am dismayed at what I’m reading on this thread from members of the biking community which represents 1% of traffic. I cannot think of a more apt usage of the adage, "People who live in glass houses should not throw stones"
If you believe that cyclists should be banned from our roads because of the actions of a minority then you must accept that it is a legitimate position for the anti-biking lobby to take towards motorcyclists.
