> I don't have much experience with non-tactile driving HUDs, but what always gets me is how, with every major version of Android, all the basic, essential functions take increasingly more screen tap counts in different places on the digitizer as they get buried deeper into submenus, calling for ever more amounts of your sensory bandwidth.

Very much this. My favorite is so small, but so, so silly. Google Play used to have a search bar at the top of the home screen. If you click it now, a little message pops up saying search has moved to a different tab. So you click that tab and STILL have to click the same area of the screen to perform a search. So many moronic design choices at these companies.
