I don't have a car so don't used my drive often, however when having deliverys or being dropped off with lots of stuff its great to get the car right he g to the front door.
As I don't used it often people keep parking over it. I would ask them to move it but its more Hassel than just parking on the road and unloading. I do mention it in passing of leave a note on the window.
They have left their car parked over my drive all weekend. I've told them not to do this, even though I don't need to access it until tomorrow morning and they will have probably gone to work it is still pissing me off that its there now.
