Here are some pictures I took of the one track lanes I spent almost a whole day driving on. Instead of thinking cars, imagine horses and carts on these very narrow lanes. I found that the ones in England were a bit scary, maybe because the drivers tended to be more aggressive. But I loved the ones in Scotland where drivers and people in general were a little more laid back.

I ended up taking a wrong turn and spent most of the day driving over 30 miles on these tiny roads that look more like driveways.
The last couple of photos on this page showed the farm that Beatrix Potter owned. After leaving her parents in her late 40s, she started buying up farms from the money she made on her Peter Rabbit books to prevent the land being developed with holiday cottages, ending up with 1,500 acres. (Her parents forbid her to get married because they wanted her around to take care of them when they were elderly, so they were very unhappy when she left home.) She later married her realtor and he also owned several farms. When they died, each donated their land to become the Lake District National Park.
Because these one-tracks were hilly, there was no speed limit, but no one drove very fast--maybe more like 25 MPH. As you can see, it would have been easy to hit a stone wall or stone building.
Being able to explore on these tiny roads is one very good reason for renting a car in the UK. I can guarantee you that tour buses NEVER take these, but what an adventure they are! (I almost ran into a wall once in Scotland on one of these roads because I was watching three cows who had their heads over the fence watching me.) I envy Tina on her current trip.
