We don't have a driveway, but there isn't a car opposite or to our right. To our left they have a whopping drive, so they're no problem. There should be plenty of space for our 1 car, keeping everyone happy. However, a house diagonally opposite to us has 4 adults, each with a car. There's also usually a wreck on their (substantial) driveway.
At one point we were parking 5 houses down the road, carrying bags of shopping and our young daughter to our house, when they can all park comfortably on their drive; but of course chose not to.
It has improved dramatically since we moved in 3 years ago though - I had a go at the daughter who now tries to park in front of our neighbours house. Mum and Dad near enough always park on the drive, or at least over their own drive. Son recently got some ear-ache regarding courtesy to neighbours and now parks further down the road (actually closer to him).
It's not as if we have a right to park directly outside our house, but there's so much available space to them with their drive or even the road closer to them that I feel it's just a case of courtesy. Thankfully, it seems to have sunk in.
/EDIT: The council have been useless too in getting a kerb dropped. Rang several times, they measured, didn't get back to us with a price, rang again and so on...
