I think that you'll find it won't be like that.
A certain amount of peer pressure would exist that would incline people away from acting stupid and more towards riding in a courteous and law abiding manner. This is certainly my experience of Holland which, on top of millions of active cyclists, has also purposefully and successfully removed large amounts of street furniture such as lines painted on the road.
Maybe it's a matter of attaining that critical density of cyclists at which culture change escalates.
