That could have been the mandate. They could have mandated that be the only allowable screen. It shows what’s behind you, and that’s it. No distractions tolerated. No pop-up logos or other advertising. No driving controls on that screen. Touch screen disabled while in motion, with all essential functions actuated by physical controls.

But they didn’t. They mandated a rearview and monitor, but didn’t restrict its use. And that failure has probably caused more injuries and deaths than it has prevented.
