Breakdown on Hurlingham Road

Regular contributor KL sends in this photo of someone pushing their bike up the hill, past the car J417LFJ parked entirely on the pavement of Hurlingham Road, St Andrews, just off Ashley Down Road.
From the front of the vehicle, you see the sign "Sorry, broken down, "

KL asks "why is it more acceptable to block the pavement than to block the road? Or was the car already parked on the pavement when it broke down?"
Actually, that bit of Hurlingham Road is a pavement that the cars have to drive up and down to get past the cars in the other direction. It was probably driving up the hill when it broke down, much to the annoyance of all the cars driving up the pavement behind it.

Incidentally, we hear a rumour -just a rumour- that Hurlingham Road is likely to be closed to through traffic, and that the closure will be at the top of the hill, not the bottom -which must mean near the junction with Cromwell Road. More details on this would be welcome.
