As a cyclicst and motorcycle rider, I think there are a few explanations.
1. Stopping and going on a bicycle is much more painful and leads to more risk taking behavior.
2. A cyclists own energy isn't nearly as scary as a motorcycle. I often find myself modeling accidents as "what if I ran into this stationary thing" which on a motorcycle you want to be preparing for as it is more likely and higher impact but on a bike. Less so. Unfortunately a moving car hitting you is the more likely scenario. Also on a motorcycle you're managing the traction of the wheels through turns, something I've rarely thought about on a bicycle. So you're just in a lower effort more vigilant headspace.
3. Cars don't feel a constant compulsion to pass motorocycles nor "go before the cyclist can slow them down". So I think the constant back and forth "getting fucked" has setup this bizarre altruistic punishment mindset in both cars and cyclists that leads to fuck bikes on the car side and fuck the laws on the bike side.
