I am always getting people parking opposite my drive and tbh, it drives me nuts. I have tackled people about it before, because I cannot get in and out of my drive when people have parked on opp side of road, directly opp my drive.
My road is very narrow, and has been further narrowed down directly outside my house slightly to the right, (as I am looking outside my front window) by a road narrowing.
When people park opp my drive, I have about a 4 foot width of road to swing my car round to drive away without bumping into the car opposite.
Since there are high kerbs as well as hedges bordering my drive from the road, I need enough room to get past these.
I have been told by the police (whom the people opposite called because I asked them to refrain from parking there to their faces, I didn't leave a note, and was quite polite) that the people opp have been told it is an offence to block a driveway, and not to park there anymore, which they still do, I might hasten to add. Last week, they had a 7.5t van sitting there from 8am til 5pm for 2 days, during which I luckily didnt go out.
There is no need for it with the people opp, they have a drive and we don't generally have parking problems where we are. They just do it every so often, for their convenience.
It is bloody annoying, but if yr happy to say if it was the other way round, you wouldn't mind doing a 30 point turn to get out of your drive, then YANBU.
