I walk to DD1's preschool along a busy, narrow B road. It seems that almost every time I go that way there is at least one car parked half on, half off the narrow pavement. Often such that I have to go onto the road with a pushchair and walking preschooler to get around the car. Or sometimes we just about squeeze past on the pavement, scraping along the wall
The road is narrow enough that other cars still have to go past in single file, so parking this way does not make it any easier for other motorists, just harder for pedestrians, especially ones with wide pushchairs or wheelchairs.
Every time I see a car like this, a brief thought goes through my mind of kicking the bumper as I go past, or knocking the wing mirror. I would never actually do it, but AIBU to fantasize?
