If they behave dangerously and put themselves at risk of being hit, even if they are the one taking the risk, the car driver will always be at fault, no matter what. And yes, like some others have echoed in comments here, many bike riders do not stop at red lights. I see that every - single - day, multiple times.
Secondly, cyclist scofflaw-ness is mostly a result of a transportation system that's hostile to them. The Dutch aren't nicer cyclists because they're born that way, superior to Americans; they're nicer cyclists because the system there largely respects people on bikes, and so the system receives respect in return.
Go to any city with widespread segregated bike lanes and bike lights, and you'll likely find a culture where cyclists are no more likely to break the law than pedestrians or motorists.
Third, motorists are hardly exempt from constant law-breaking. How often do people not signal, or roll through stop signs, or enter the intersection right after the light turns red, or park in a bike lane, or 'block the box', or tailgate, or break the speed limit? I've lived in enough places in the US to know that the answer is "constantly". And all that with a vehicle that's vastly more dangerous than any bike or jogger.
I mean, my god, one of the most common and stereotypical complaints in America about where anyone lives is "ugh, drivers in [state] are the WORST".
This is like complaining that people treat guns and knives with different levels of seriousness. Of course they do; both are potentially deadly, but one far more so than the other.
