At what point is a car not within the lines of a space?

If you lived in Paris not so long ago you would expect to be backed into or driven into at both ends by people parking and unparking. The idea was to leave your handbrake off on the flat and steering straight so your car moves up and down with the arrival and departure of others. Dents were expected. It's also what bumpers were for. Not sure how it works with these daft plastic bumpers. You should be able to get city bumpers or add on fenders for cars like the Roo bars on 4x4s. IMO

While I'm not overly chuffed with the idea of self-drive cars, I would love it if one day cars were able to shuffle themselves about whilst parked to make up for their owner's lack of spatial awareness. I don't mean leaving 1" at either end when parallel parked, but at least being able to sort it out when some dhead has parked slap bang in the middle of a space 2.5 car lengths long.
