Columnist: The failure of bicyclists to obey traffic regulations is a causal factor in more than one quarter of the traffic accidents involving bicycles. Since inadequate bicycle safety equipment is also a factor in more than a quarter of such accidents, bicyclists are at least partially responsible for more than half of the traffic accidents involving bicycles.

The columnist's reasoning is flawed in that it
presumes, without providing justification, that motorists are a factor in less than half of the traffic accidents involving bicycles
improperly infers the presence of a causal connection on the basis of a correlation
fails to consider the possibility that more than one factor may contribute to a given accident
fails to provide the source of the figures it cites
fails to consider that the severity of injuries to bicyclists from traffic accidents can vary widely
