I fully agree with you Ianski.
I rather think, those that are parking on pavements are doing so less to inconvenience other car drivers, but more to diminish the chance of their vehicle being clobbered by someone squeezing past. It is pure selfishness. Much the same as those who feel their journey is taking far too long, will race through residential areas, and couldn't give a monkey's for their speed.
A friend (who has a drive), who lives close to one of the many schools round our way, and the one closest to him had a Open Evening. He stood outside his house to watch a woman pull up across his drive to park and, getting out said: "I won't be long!" She was off to the school. He said: "I can't get my car out! She said: "But I won't be long!!!" He told her, if she left it there it wouldn't be in the same state as it arrived. She huffed and puffed and then tore off down the road. Unbelievable really. It happened to him on the following evening, when somebody parked across his drive, so he walked up and down the road knocking on people's doors to see if anyone knew who's car it was. Nobody did, so he then got a friend with a big Land Rover to haul it down the road. Maybe they'll learn? Who knows.
