Nowhere, that's where.
Right of egress? Pah! Nobody gives a shit. Common-sense says "park with due consideration", but the M.O. is "park anywhere, and complain when asked to move".
Our driveway is blocked and I can't get my car out. My neighbour's driveway is blocked and he can't get his car out. The flat where the work is being done has no driveway and the residents have no car.
Go figure!
