I bike for 90% of my traveling. The examples you give for when cars break the rules vs what bikes do is telling. Yes, everyone breaks the rules, but cars (mostly) do it in safe and predictable manners. Most urban cyclists(including me tbh) break rules in very unsafe ways. Bikes routinely completely ignore stop signs even when there are cars waiting. The ignore red lights which cars never do. They swerve around in traffic, they ride on the sidewalk. Many refuse to use lights when biking at night. Urban biking behavior in the US is on average much more reckless than driving behavior.

Cars are more dangerous due to size and speed but if we’re just talking about who acts more recklessly and ignores more rules it’s easily bikes, at least in Chicago.
