Was just about to say the same thing, Peter! 😀
I’ve seen the (very rare) car up there, and I’ve seen what I presume is the farmer using the tarmac path to get a 4×4 into the neighbouring field. I know there’s also a regular dog-walker that often parks their vehicle at the South end of it (courteously, off to one side of the path) around 09:30 on weekdays.
Given that I’m also “illegally” using the path every morning by cycling up it, I’m not sure I’m in a great position to complain! 😛
