TomTom frequently comes up with some weird routes if left to its own devices. When I took stuff to my wife in hospital the first time it took me on a 'road' which I don't think had been resurfaced since the Romans left. It was a sunken lane with banks so high my head was level with the roots of the hedges and really narrow. Needless to say I have not repeated that route since. Garmin often does this. With some unexpected views
And she was going pretty quick and the rubble in the middle off the “ road” made it difficult to pass. Been there. Also the herd of cows, the flock of sheep, local hunt, bloody artic with a load of logs coming up a hill I was going down (in Ireland and I ended up in a field), hysterical horse that had dumped it's rider etc. Small rural lanes are often more interesting than you'd think!
