I’ve had that myself but with on street parking that’s enforcible.
I pulled up in a BB space and within a few seconds a parking warden was about to tap on the window when he clocked the adaptions on the steering wheel and with that he doffed his cap and walked off down the road.
I don’t mind being challenged by wardens or police TBH and gives me hope they are catching violators sometimes,
rox like you say the spaces aren’t enforcible on private land but there was a time that your public road insurance didn’t apply on private land but it does now so we live in hope.
