I’m not sure it’s comparable. There’s a lot of information you need to keep an eye on when flying. Speed, altitude, attitude, coordination, heading, position, etc. Lose track of any of those and you can get behind the airplane and crash.
In a car, you sorta need to know your speed, and that’s it. Even speed is not entirely necessary. In an ICE car you also might want to keep an eye on engine RPM, oil temperature, and other such things, but you don’t need them in an EV
If all your instruments go out in an airplane, it’s an emergency. Depending on the aircraft type and situation, it may mean certain death. If it happens in a car... I’m not convinced most drivers would even notice. Those who do would only be mildly inconvenienced at worst.
Edit: here’s an example of an airplane with side by side seating and a central instrument panel: https://www.pipistrel-usa.com/taurus/. Gliders are much more car-like in their instrumentation needs, although they still need a bit more, and losing them all is still an emergency.
