Why do cyclists enjoy being the most arrogant road users.?

Because we were here first.  Cars keep clogging up our roadways.  Fact: the first paved roads came about because of petitions to Congress from cyclists.

Choke on it.  

Judging from your question, I'd have to say that the competition for "most arrogant" has not yet been won.

Just stick to getting that PIMP tattoo, it's about all you seem capable of.

They are scum. I enjoy seeing them get hit by cars.

Because they know that bikes was invented before cars and they have more rights on the road than the motorists. I hate them too.

Many of them seem to have a holier-than-thou attitude because they think they are saving the environment. They also think they have just as much of a right to be on the road and they never have to yield to cars, even though they are much smaller, have no brake lights/turn signals, dart out from nowhere, and seem to have no sense of self-preservation and no brains. Not all of them are like that, but many of them seem to be and it is really frustrating. I am always afraid of accidentally hitting one and having them freak out and take me to court or something even though there is no way I could avoid them. 

Arrogant? When I ride my bike down a two-lane road some drivers are too afraid to pass me. I pulled over to let them by. What's wrong with that? 

I would say that someone who "enjoys seeing cyclists getting hit" hasn't ridden a bicycle on city streets, so I would ask, "What are you AFRAID of?"
