@cstross When my SO and I moved from Sweden to England at the turn of the millennium, we brought our old manual car over, on the principle that if we were familiar with the controls we'd only have to learn to drive on the left side (and roundabouts!) to start with.
When we replaced it with one that had the driver on the right side, we got an automatic, as my SO is too right-handed to shift gears with her left hand. After that we only had automatics in England.
Now that we've moved back to Sweden, we've bought a manual car again. Took a bit of practice but we've both got the muscle memory back now.
I'm sure those who've automated as much as possible could learn to drive without those features again. What scares me is that they don't think they can.
