I'm positive this is what happened. My anecodotal evidence: the touchscreen-while-moving functionality was removed when my 2016 got a software update. One day I could just touch the giant map to enlarge it, the next I had to twiddle the knob a precise number of notches and watch the screen to make sure I highlighted it correctly.
It could be worse: Lexus infotainment screens of certain years would refuse to display the radio's RDS song info when you pressed the "Message" button (which enlarges the window to see it) while you were moving. Meanwhile, the RDS data happily continued to scroll by, one word every 3 seconds, in the tiny marquee at the top.
