Someone said earlier that just one case of an accident involving XYZ is enough to warrant a ban. What do you think?
Certainly, bicycles and cyclists are quite vulnerable, hence the need for (ideally separated) cycle lanes, obviously free of obstacles such as parked vehicles. Close passes and similar violations should be mercilessly prosecuted - the only way that will happen is that cyclists wear cameras and report the incidents. CCTV might get smart enough to do that automatically, but we are probably not quite there yet (or the solutions would not be within the budget), could be wrong! Incidents where cyclists get hurt and a car driver is at fault should be met with particularly punitive measures due to this extra vulnerability, I imagine not the case at the moment. Of course, someone will jump in momentarily to argue it's all good fun out there for cyclists in London
