It's like that in my city too when people decide to drive on the streets designated as greenways. You want bikers out of your way? Give them another place to go and they'll gladly use it to get away from you. It sounds like you're describing a place where there is only car infrastructure so bikers are forced into traffic situations built for cars. That means every one of them interprets what they are supposed to be doing (either for safety or to follow the law) differently.

Think about it this way. Someone parked in the bike lane? I'm swerving into traffic. Person doesn't see me and starts merging at me? I'm swerving into another lane. Someone intentionally decides to ride my ass? I'm getting out of their way before they get violent, possibly putting me in front of you.

Tired of bikers in your 'car lanes'? Give them their own lane. A person in a car does not have any more value or rights than a person on a bike. And their infrastructure costs tons more.
