My Audi has a knob which I can rotate in order to navigate through the menus without taking my eyes off the street. It also has a touch screen, but I only use it when standing still.
Mazda has something similar. I realized that "do __ without taking your eyes off the road" isn't really true, for the same reason that it's hard to read your phone and listen to someone at the same time. Most of the time you can strike a balance, but every once and a while your mind will completely blank and take a few moments to realize you stopped processing what you were hearing. Not a risk worth taking while driving.
I try to avoid using the knob while in motion as well.
There's also a difference between taking your eyes off the road momentarily to look at a simple predictable display in a fixed location, like a light or a needle or a fixed text display, and taking your eyes off the road indefinitely to look at a screen that displays something unpredictable, complex and arbitrary as part of an interactive session, usually with animations.
Do you refuse to ride in Ubers, or avoid Amazon delivery vehicles? I have to admit that the level of tech-denial in this thread seems to be getting out of hand. Everyone uses in-vehicles maps. Everyone deploys them on touch screens. They're pervasive and everywhere, and none of the arguments change when you bolt them to the dash.
Why is "Tesla" being held to a different standard than UPS/FedEx/Amazon/Uber/Doordash/etc...?
I would say because Tesla is doing something similar to this (well, not the ditching, but the bad part that comes before the eventual ditching) and basically what the study found:
Navy ditches touchscreens for knobs and dials after fatal crash
Things did get diverted on a maps drove tangent but that usually on our pose to enable the same argument you're making now.
The argument started by asking why windshield wipers, environment controls or basic radio functions need to be buried in a touch screen.
Also most vehicles limit what's allowed in navigation screens while the vehicle is moving. Which is annoying when it prevents a passenger get from using it but sensible when there is a single driver.
