I don't see what else the driver could have done in all honesty, maybe hand the back of the van out of a space and be a hazard - I would suggest if posting things like this then it's good practice to make a recommendation on what you would have done, and how you would have parked.
Otherwise it's just a silly post for the sake of posting something.
Pricks do exist. And they exist because they think there are no consequences. It may be tough to do it these days but perhaps if this happens again drive to the nearest police station, if there's any still open, or at least report it straight away to 101 or 999.
It’s registered as a spacker chariot, so probably driven some old blind cunt, or a fat woman who is too bone idle to work.
