Maybe not as profound or important as the Civil Rights movement. But important nonetheless for public safety. (Assuming the guerrilla bike lanes themselves are safe and well thought out.)

That said, in my experience, cyclists are the #1 group when it comes to disobeying traffic rules. There are a lot of crazy idiots driving cars or riding motorcycles but at least the vast majority of them stops at a red light, doesn't ride on the sidewalk, doesn't go against one-ways, etc.
