We have a 2 car per household rule in our estate. Across the road the neighbours have 5 currently. They park willy nilly sometimes making it impossible to get out of our own driveway. They park 2 in their drive (belonging to the same family member) and three on street (one being someone who hasn't even passed nor drives it) be it in front of our drive or outside our house so they have clear access at all times. Rule also states both cars must be in own drives. Aibu to want to put in a complaint?
