I hate those. I once were on a very tightly packed street that ended abruptly. Cars on the left and right side. I had to turn around, but I couldn’t do it anywhere. So I went in reverse, saw one parking space open, backed up in and scratched my rear end with a chain dangling so it’s perfectly invisible from a car.
