I did this to a Corvette owner last week, except that I parked fully in one space. Holy shit was he mad. And he couldn't even admit that was he was doing was shitty and disrespectful to everyone else around him; he just kept saying that he paid a lot of money for his car and didn't want it getting scratched. He was too overweight to get in the passenger side and crawl into the driver's seat, so he had some other dude do it for him. If he'd just admitted to being in the wrong and agreed to not do it again, I would have moved; I even told him that. But his ego wouldn't allow for it.
I'm probably going to get shot by one of these douchebags one day. I should probably remember to carry more often.
