And I should add that I suspect there's a technology stage issue here. If you look at a model T dashboard, the controls were by modern standards terrible. All of us are used to cars where they spent decades refining physical controls, all of which were pretty uncomplicated compared to what we routinely expect software to do. So it's reasonable to me that if we count the number and severity of driver experience issues, the graph bottoms out sometime in the mid-1980s (1986 being the first time they put touch-screens in cars).
