An interesting one regarding driveways - according to a builder friend of mine (who is very clued up on these matters), it is not illegal to park, on the road, in front of someone's driveway, if the driveway is empty!
I dont condone it, but it's true, as far as im aware.
Anyway, "raggy roman" dude - i would assume that with each house sold, a private car parking space (off the council's road) was included in the price - as with many new build flats and appartments these days.
If a non resident comes along and parks in one of those spaces, then they are surely in the wrong.
That space, on private land, has been paid for and is owned, therefore only the resident owner has the right to park there.
Where's the problem??
All the residents in the area should invest in some wheel clamps.....if the rogue parkers show up and park their motors, clamp them! lol
