Actually, studies have shown that motorists are the biggest traffic rules offenders. The thing is cyclists who are running the lights are more visible because it triggers the jealousy of other users having to wait who thus ignore the majority of cyclists who are actually abiding to the rules and waiting, and the huge amount of motorists who floor the accelerator and run the light after it changes (and is only a small fraction of all the rules they don't follow). The other reasons some motorists feel cyclists obey less to the rules is because motorists feel more entitled to bend them at their wishes than other, the worse at that being the one driving as part of their professional duties.
