It's both an infrastructure and driver behavior problem. As a daily transportation cyclist for about 10 years, I know from experience that much bike infrastructure in the US is more safety theater than actual safety improvements. Infrastructure makes cyclists feel safer, but it can amplify certain problems to the point where it might be making the roads less safe. There are two cycletracks near where I work in Austin. I almost never ride on either, mostly because many drivers turn into them at intersections without looking. The city put up many signs to say to yield to cyclists, but these have had no effect best I can tell. I'd much rather take the lane and be seen. This is counterintuitive to many people, particularly non-cyclists, but the evidence I've seen in my daily life is overwhelming. These types of crashes are often called "right hooks" and they are well known to experienced cyclists. Add on top of that the unsafe passes from drivers. Add the distracted driving. Add the speeding. Add the illegal parking in the bike lane (even protected lanes). Add the tailgating. Add the abuse from thankfully a far smaller number of people than any of the mentioned problems. It's clear to me that both infrastructure and behavior changes are needed.
