What does this picture show: it shows a very large lorry squeezing past a pickup that got the demi-drive parking wrong. They forgot the rule "don't stick out past the pavement". Indeed, the whole purpose of pavement parking is to ensure your wing mirror will still be there when you get back, your paintwork and bumpers unscathed.
You can only do that if you know that the width of the road left behind is greater than the maximum width of the vehicle that wishes to pass. For the lorry drivers, it's pretty inconvenient.
I think this one just made it past the van without causing problems. And if not, there's a small garage further up this alleyway off Cotham-Hill who would be happy to pick up the repairs.
