I don't really agree that the Land Rover is actually difficult to use.
The Defender is really actually very simple to use - it's simply unrefined. There is a clutch pedal, a brake pedal, and an accelerator. If you want to have ventilation, you open two flaps in the front of the bulkhead with two levers. If you want to shift gears, you do. There is a lever that locks the center differential and also engages low or high gear.
I don't see how a modern vehicle with its almost endless clusters of displays, switches, and buttons is somehow easier to use than a Landy.
