There's a gang of black cars here, and it looks like everybody was getting along just fine until someone decided they didn't want to be like everybody else. It's never acceptable to park sideways when nobody else is. We have no idea why anyone would ever believe that to be the case. If it ever happens, we're always pleased to see other drivers taking action about it, as they have here.
No less than three other drivers have got involved in making sure that this parking joker has nowhere to go when they come back for their vehicle (unless they want to take a sharp right and risk high-tailing it across a building site) and so there's going to be an awkward conversation. We wonder if they'll be asked to hand in their membership card for the black car club? That might be the greatest punishment of them all!
