If you're lucky enough to have a nice vehicle, do your fellow gearheads a favor and don't park like a clown. Seriously. Not only will you anger everyone who is trying to find a place to park, but your nice car is a billboard reinforcing the stereotype that car people are self-important and inconsiderate.
Take this gentleman for example. He has a Jaguar XK, and understandably wants to take care of it. Rather than parking it far, far away from any other cars and getting a bit of exercise by walking to his building, he takes up two spots (albeit barely) close to the structure. From the cameraman's narration, we can tell his coworkers are less than thrilled about his inability to stay between the lines.
Naturally, they wanted to teach him a lesson, so they parked a bigger vehicle as close to his driver's door as possible. Mr. XK's attempts to enter his vehicle are rather amusing, culminating in his climbing through the passenger side and scooching over to the driver's seat. While we can debate this sort of treatment all day long, it was effective. The video includes a follow up at the end showing where the XK driver parked the next day, and as you might guess, it wasn't in the same spot.
Take a look at the full video below, and remember, be a considerate car person.
