I have nothing against cyclists as long as they act sensibly. It get's my gaul when they go across red lights but this seems to be getting better since the police have been catching them and issuing fines. Drivers in Norwich moan when cyclists use the road instead of the expensive cycle paths provided!
Part of the problem with that is the people who design cycle paths don't cycle, many of the paths around Norwich are shockingly bad design. We have one cycle path locally where a foot path crosses the cycle path that is parallel to the road, the part where the footpath crosses the cycle path has a chicane so cyclists have to stop and wheel the bike around but there are no measures on the road to slow down cars so no sensible cyclist bothers using the path in the first place.
I would also hazard a guess that the same people who would quite happily ride off after causing an accident when they are cycling are exactly the same people who when driving a vehicle drive off and do not stop if they cause an accident. However for some reason the very small number of cyclists who do this seem to be disproportionately reported in the press but when people who do this in a car you don't hear much of it (probably because it happens so often it's not "news"). I've personally been hit by car mirrors twice while cycling because the drivers were not overtaking sensibly (and no, I wasn't in a group as I cycle by myself!) and neither time did they stop, I guess that the drivers didn't feel a needn't need to even attempt to cross the white lines on a dual width road while they were overtaking!
