Earlier quoted context omitted.
You can turn off your phone or go into airplane mode. Can you do that with your car? Even if most people don't use that option on a daily basis, doesn't mean it's fine.
So you put it in airplane mode while in a car and then disable airplane mode when you get to your destination? What's the point of that?
Why would I need to disable it? If you're not using the built-in navigation (which probably costs money anyways) and are using carplay/android auto instead, you should be able to leave it in airplane mode indefinitely. What critical functionality would I be missing out on?
