Due to designed traffic pattern - like at Florida Publix lots with one way
LOL. Traffic pattern. One way.
More and more, I've found parking lots a free for all, and one way or not, it doesn't matter. Arrows, lanes, and lines have no meaning. Waiting for someone to back into a spot is the least of any problem.
There's one local lot where a one way parking lane exits very close to the lot entrance. Despite the prominent no turn/do not enter signs, they are regularly ignored. Blind? Just plain stupid? Or just don't care? Who knows. A traffic cop would have a field day every day if that was a stakeout spot.
