Properly used screens are great. We all grew up and learned to scan the instrument panel of our vehicles with just a momentary downward glance. As long as everything was good it didn't even register we did it. But if something was wrong out eyes were immediately drawn to it.
I went to work in refineries when most of the plants still had pneumatic instrumentation (except for temperature) and controls. Everything was related with a 3 to 15 psi air signal. Control panels would be 20 feet long and 6 foot or more high. A good operator could essentially do the same thing we did in cars. No matter what they were doing you'd see the eyes dart to the board and scan every readout. All and never miss a bite of donut.
Early computer controlled systems used monochrome displays. A bank of displays maybe a third the length and only a couple of monitors high held all the same info. Those operators could do the same thing again. Heck, I ran one control room for two units, one was pneumatic, the other computer controlled. It did take a beat to learn how to switch gears in mid glance from pneumatic to computer. But it wasn't anything every other operator in tht unit wasn't doing.
So now we have vehicles with screens. Most can be customized. If one customizes the information they can scan not only the instrument panel but the lcd as well. It's not the screens, it's the info allowed on the screens while the vehicle is in motion that is the problem. Turn off phone functions while driving, shutdown video displays showing movies and TV. Limit what can be done as far as audio tuning. If folks are fooling with these sorts of things, if all they can see is vehicle related information, they'd learn to scan the panel and the lcd in the same way we have always done.
