There's some minority of people who are just jerks on the road. Drivers that don't account for other road users. Cyclists who blow through intersections forcing cars and pedestrians to take evasive action. Pedestrians that expect wheeled vehicles to defy the laws of physics on their behalf.

Beyond this minority damn near every road user (regardless of car vs bike vs pedestrian) behaves perfectly reasonably if you understand what they're trying to do. Once you understand what the other participants are trying to do things become very predictable and safe. The road user who is constantly having problems is probably doing it wrong themselves in a "man who smells crap all day should look under his own shoe" sort of way.

Crappy cyclists make crappy pedestrians make crappy drivers.

I've biked walked and driven at various points in my life. If you understand what everyone else is doing and choose your own actions to mesh with this you basically never have problems with other road users. You can blow through intersections on a bike. You can jaywalk. You can ignore turn specific arrows. You can do all these things safely. But you gotta have good situational awareness exercise good judgement about the time and the place you choose to do them or you will often be in conflict with other road users.
