My drive is not the issue - the heavily cambered road is, it has a huge crown on it and hasn't been resurfaced in years, meaning the profile changes between the middle of the road and the gutter/drop kerb by about a foot and a half.
Many years ago I lived on a quiet side road that was like that and used it to my advantage a couple of times when I needed to work under the car (parked with one end on the pavement and the other in the road)
