Public Highway in Somerset

It is called 'Sunny Lane', and is between Bruton and Cole. There is a tearoom at Cole and the satnav selected this, the most direct route. There are no crossing places and it is mostly a steep hill.
I went back on foot to photograph it and met a car with two passengers descending as I had done an hour before. I pressed myself into the bank and the car stopped briefly. The passenger said that the satnav had brought them this way. They were en route to Cornwall. I still can't work out how Sunny Hill becomes part of a journey from Somerset to Cornwall.
