I see cars driving 50km/h in a 30km/h area multiple times a day.

Everyone breaks the traffic laws, it's just that for cars it's about speed (speed limits, illegal overtaking etc) while for cyclists it's about momentum (running red lights, stop signs etc). Both are dangerous behaviors that put others at risk

Citation needed for cyclists running stop signs being dangerous. There have been numerous studies showing that at least for stop signs, it's actually safer/neutral. Anecdotally, treating stop signs as yields for biking encourages me to ride on more neighborhood streets with stop signs instead of full on signals; additionally, while stopping has negligible benefit in terms of yielding to cross traffic, doing a full stop each time means it will take much longer for me to cross the intersection which is the most dangerous part of the road.

I see idiots at least twice a day. Does that mean it’s cool for me to treat you like an idiot? If no, then I think you may have skipped over the point of this sub thread.

I live in suburbs between San Jose and San Francisco, and haven't driven in a while but on a typical car trip I see someone run almost every other light at busy intersections, seeing a motor vehicle come to a full stop at a stop sign is rarity as well unless there is a law enforcement vehicle watching. I have learned to wait after a light turns green for me defensively to make sure someone else has not decided to gun it and run the light.
