I find this an interesting thread for I too have issues with parked cars.
I am on a curve in the road and the dropped kerb in front of my gates is not 100% in the right position anyway (I think the curve confused whoever marked it out). Even if someone parks up to the drop it makes life difficult, and usually they are over it.
I have a small length to my right that is just big enough for a small town car, but which often gets blooming big vans stuck there. Also a larger length to my left, which a neighbour from down the road a bit tends to shove his van on.
This causes a hazard as folk shoot around the corner expecting nothing to be in the way (car, child, whatever) and if I am edging out they have to brake sharply and have the cheek to cuss me for their own reckless driving !
That aside, it is difficult enough to get out at that, but directly across the road it isn't uncommon for others to park one or two cars; and quite honestly I can't understand how I've managed to get in and out sometimes without scraping one of more of them. I have little room to drive out and next to nothing to turn in.
Having bought a place with a drive is nice, but folk taking up their right to park at the kerb makes things nearly impossible much of the time. No wonder many in the street have knocked down the whole of their front boundary wall and dropped the kerb across the whole width.
It's a retrograde step for the community, not something I approve of, but the way things are going folk end up thinking they have little choice any more.
