I confess this is me in all modes of transportation.
I usually bike and I follow the rules but bend them when I think it's safe or, quite frankly, most convenient. Same with driving. And walking. And I hate every non-bus thing slowing me down when I'm on a bus.
One mode being more disrespectful than the other isn't the issue. As others have said, as mixed mode transit continues to increase, any anomalies seen from subsets of a given population should be balanced out by the crowd. So, it isn't that cyclists break more laws, merely that they break DIFFERENT laws than cars. This isn't my opinion. It's this guy's:

So let's put aside the us-vs-them for a moment and assume for the sake of argument that all travelers will make the same efforts to get to their destination as any other traveler using a different mode, and will take advantage of the benefits of their respective mode (speed, bus lane, alternate routes for bikes). Assuming again that each mode will bend or break the rules in equal amount, which is the most dangerous mode? We all know the answer to that. (It's cars

A more troubling concern I have is that driving not only is the most dangerous mode when we all behave the same, it's also that drivers have more indications of extremely dangerous behavior outside the norm. Intentionally killing people because of travel rage is pretty much exclusive to cars. I found lots of examples of car on car rage incidents. Then I tried to find something involving bicycle road rage causing a death. Google "bicycle rage kills" and all you get is cyclists getting murdered by cars.

If I never biked another day in my life and got everywhere by car, sitting in traffic I'd probably hate everything (bikes, walkers, and cars) that was cutting me off and slowing me down. I'd be as bitchy as our anti-bike friend on this thread and blame the other modes for screwing up the whole system. I'd be (a) selfish, (b) rude, and (c) impatient. I'd think I was right. And I'd be wrong.
