Was just in Copenhagen for ten days.  For major roads, they have great bike lanes almost three bikes wide separated from the cars with a curb.  Minor roads don't have the curb separation.   
Don't know exactly how they do it but virtually all cyclists obey the rules of the road and almost everyone that is physically able cycles, young and old.   Didn't see anyone racing.  Didn't see one bike go down and I was on the streets a lot.  Having so many parents, mostly women, carrying their young children with them  in bike carriers may have something to do with it.    One can't help but feel a shared responsibility for their safety, something that is missing on Toronto roads.  
Toronto cycling is dominated by one demographic, the young and fit. It's too dangerous for almost everyone else.   If we want to improve cycling in this city, we first have make it safe for everyone to cycle.  Then more people will cycle.   Ironically, I think the more people that cycle, the safer it will get.
