Well, maybe it's because it extends 3 feet into the street. I've actually knocked it off twice. Each time, I kept going until it cooled off. Dude, this ain't central oregon and these streets are narrow. You are like a 5'2 dude in a monster truck and you work at best buy or target or some shit judging by your polo work shirt.
If you want to keep buying mirrors, that's cool. Otherwise, park your f750 or whatever, in the driveway or maybe trade it in for a smart car. Btw, there is a scrawny little shit driving a newer mustang, that comes over and (I'm guessing here) fucks your gal while you are peddling lawn chairs. Just a heads up.
