What are you afraid of whilst cycling

hammering along in areas with lots of parked cars and children playing, with poor lines of sight is not the most sensible thing to do.

there tend to be a lot of constriction points, narrowings where there are cars on both sides of the road etc. so trying to race in such areas will often involve riding very close to parked cars, reducing your view of pedestrians walking out etc

This is the diatribe of a weak, weak man.
