This is where the law is made to be a laughing stock, and we might be able to change this in Scotland with some powerful lobbying.
To park in that position the car has to have been driven on the footway (pavement is an ambiguous term - it refers to any paved surface and in the US generally refers to the carriageway) riding or driving a carriage on the footway as been an offence since 1835 and the same deal applies to both cycles and motor cars, and road locomotives.... each being embraced by the term carriage in enabling legislation (cycles beating cars by 25 years IIRC).
Thus, observing the sheer number of cars with wheels on the footway, a far greater number of drivers should be getting FPN's for using the footway than cyclists - a detail confirmed by the number of pedestrians killed and injured by cars driven on the footway.
Now here's the rub, a parked car is not being driven on the footway and there is no driver present to charge with the offence, so although everyone knows the offence has to have been committed (the cars don't simply bounce up onto the footway), so the Police don't prosecute - unless they go for obstruction - preventing 'traffic' ie traffic proceeding on foot, from passing along the footway.
Yet prosecutions of the registered keeper of the car can take place if a photograph of the vehicle, is taken - going past a red traffic signal, exceeding the speed limit, using a road over which that vehicle is not permitted to travel, and even used to affirm obstruction and parking offences, and the registered keeper is obliged to provide details of the driver, or take the hit themselves. yet this same logic cannot be applied to a motor vehicle parked with 2 or more wheels on the footway. It shouldn't take much to amend legislation surely - to make a photograph of a vehicle with its wheels on a footway enough to use the existing law effectively.
Plus of course it would be great to get a real figure for car drivers committing the offence for which cyclists are so often pilloried.
Anyway the driver should still be getting as parking ticket for parking on a single yellow line, as 2 wheels are on the road at that point.
