I'd love to see similar testing conducted on "consumer" avionics boxes used in general aviation. Garmin has moved many of their units from fully-tactile buttons and knobs to touchscreens. This puts the onus on the pilot to fully master the system before entering a situation where you can't simply swipe/scroll your way to success. But using a touch screen in turbulence is nearly impossible; Garmin engineered a physical lip edge around the unit to hang onto to assist the pilot in stabilizing their finger.
There's a reason professional cockpits still largely eschew touchscreens when 250+ lives are at stake in the back.
