Despite what your first impressions may tell you, this isn't a photo showing multiple people parking terribly at the same time. It's a photo of one person parking terribly, and then multiple other people joining forces to teach them a lesson. Whoever owns that big white 4x4 at the center of the picture decided that diagonal parking across multiple bays was fine, and so the other five drivers decided to prove to them that it wasn't.
If we had to guess, we'd say that this car park belongs to a large office building, and all of the cars belong to someone who works in it. That means the original offender is going to have to make multiple inquiries as to who they're now going to have to ask to move so they can get out - and they'll have to explain themselves multiple times when they do it. That had to be humiliating.
