I think you'll find this true in most places, at least in the US. The main differentiating factor is probably the consequences - or lack of. Disobey traffic laws and get caught in a car or motorcycle - you face consequences that can range from harsh to at least significantly annoying enough that you'd rather not. Do the same in a bike, and most people don't care beyond giving you the finger or a nasty look. Even cops don't care more often than not. True - you don't have a cage of steel surrounding you like in a car so you also risk being killed or maimed, but I've found most cyclists also have a sense of invincibility until they actually get hurt. I am guilty of this myself.
