There must be a GPS locator phone app everyone has which shows people where I am parked in parking lots, obscure highway pullouts, national forests, etc. so they can come and park right next to me.
I may be one of these people. At least for the more obscure places, the highway pullouts and national forests and things, if I see another person parked there, I’ll typically park next to them. Safety in numbers, the more people parked in a turnout, the more legitimate it looks to park there
Post doesn't complain about them parking super close so as to make opening the door difficult.
I agree with the other commenter. Parking next to someone makes it look more legitimate. Or perhaps that person knows better where it is legal to park.
Parking should follow urinal rules. Never use the stall right next to someone else unless it is the only remaining option. And especially if there is only one person at the urinals so far...
