It's illegal anyway - but if you're blocking the pavement so that a person in a wheelchair or a person pushing a pram or buggy is forced out on the road to pass the car, it's at least inconveniencing and potentially seriously endangering them. The inconvenience isn't minor either. Have you tried negotiating multiple kerbs in a wheelchair because someone's blocking the path? I've seen people having to do that, and it can mean moving backwards to the nearest point the kerb is dished, around the vehicle, and then unable to get back onto the kerb for another few metres afterwards.I dunno what the fuss is about. I'll bet most people here have parked wheels up on a pavement at some point.
That's what the fuss is about.
