It's not clear from the clip if there was something on the inside of the car that could have caused it to move over, and I doubt the cyclists had checked either.
It's nothing to do with 'hurting feelings' that's not really a credible argument. It's more a case of keeping clear and consistent rules, as if they're not, then the confusion causes frustration, which is no good for anyone.
There does appear to be a bush protruding slightly into the road, and they passed each other away from the parked vehicle, so the cyclist could have adjusted their position to have passed further away from the car. They actually appear to move toward it prior to reaching the parked car.
The obstruction is clearly in the cyclists lane, so the responsibility lays with them imho.
Clearly the Police and the Courts disagree with me, but then others have disagreed with decisions not to prosecute on clearer evidence than this.
