Self driving, my arse
Hopefully this URL should get you to the place I intended! Near Diptford in Devon:

"Drive" towards the farm on the right in the distance and try and imagine parking (the slope down is about 33%). Easy for a human in summer, quite tricky for a tractor in winter. Now try getting to Diptford or Harbertonford and thence to the mighty metropolis of Totnes.
How do you tell a car to ignore the fact that both wing mirrors are brushing through hedges and that avoiding that pot hole will involve a heavy session with the T cut later on but that's better than a broken tyre/axle/death? What does it do at a ford?
That was easy, now try driving around Napoli or as I call it: "bumper cars".
Also, it will need to be able to play "I spy" and be able to find a safe place to stop and extricate little Johnny for a wee or a dump ...
I suggest we add a few more levels after 5.
