I have a very simple rule. Traffic laws and enforcement of said laws should be proportional to the accident rate.

If the average car driver has 2x, 10x, 100x or anything like higher accident rate than cyclists, and car traffic is several time larger than bike traffic, then it make logical sense that most traffic law and enforcement is put on addressing car traffic and drivers. The only consideration is when funding for such enforcement and laws don't follow strict scaling, in which you have to find the point where putting more funding in bike traffic laws actually produce lower accidents.
