That SUV is quite a 'hoss'. I'm not surprised at your experience driving it in the UK.
Some 5 years ago I spent ~2 weeks driving around England. As an American, the wide variety and quality of UK roads was an eye opener. The motorways and most of the A lettered, even the B roads, were good enough for driving. But the small narrow country lanes – with no letter or number & without shoulders – could be terrifying. These roads were never straight & were usually surrounded by high hedges or stone walls, making it impossible to see oncoming cars or trucks. Yes, large trucks! These roads were so narrow that there was barely enough room for you & any oncoming traffic. After 10 or 20 miles of stressful driving on these roads, I was exhausted. To keep driving distances as short as possible, the SatNav/GPS apps directed us away from roads with wider pavement & painted lane lines, & instead guided us onto those small narrow country lanes – without shoulders.
Blindly following the SatNav/GPS guidance led me into so many white knuckle moments that I was exhausted. I eventually learned to buy a small map that showed the M, A, or B roads. They may have been less direct, but were far easier to drive.
