I live in a condo building, so parking stalls in my building are already a little smaller than usual. The guy who parks next to me own a full-size GMC Crew Cab Sierra, which takes up a a significant portion of his stall resulting in his mirrors hanging out into the stall on both sides. To make things worse, he doesn't always park his truck straight or even in the stall (the guy who lived in the unit before him owned a Nissan Titan and, to his credit, was always able to park it straight and even).
I've asked him to fold his mirrors in when he parks, which he does 90% of the time. But when he doesn't, I've considered folding his mirrors in for him because otherwise I'm barely clearing both his mirror on one side and some structural columns on the other. Do you consider it offside to fold his mirror in?
