Exactly - a law unto themselves. The attitude of the majority of them (especially 'experienced' cyclists in all their fancy gear) is disgraceful; aggressive and inflammatory. Half the time I'm apprehensive to overtake them in case they attempt or gesture to kick the car or shout verbal profanities at me or my fellow passengers, or something else to that effect. It's about give and take, and as far as I can see (and have experience with) all they do is take.
Keep them away from motorways at all costs. In fact, it should be mandatory that all cyclists who wish to use public roads have to partake in some form of education and training. They need to get rid of their superiority complex, realise that they're not invincible and learn that applying rules specifically intended for vehicles to them, is ridiculous (and instead, abide by rules specifically tailored to them). Maybe then we'd have less cycling-related road deaths.
