Being honest here, I have a car with android auto and I hate having to plug it in for a variety of reasons.

1. I just want to get in and drive, the music should just play and all the stuff should just get out of the way.

2. I don't want to charge my phone every time I drive my car, it's not necessary and can be hard on the battery

3. This is doubly important for an EV, I don't want to waste EV power charging a phone that doesn't need charging

My opinion, Phone OS makers need to get their shit together around android auto / apple carplay. Too much nonsense gets in the way of all the actually important pieces. When you get in a car with only a radio, the music just starts playing when you get in. Which means, your experience is better with old tech. That's just ridiculous.

I personally think a better idea is to just start equipping cars with cell modems that you add to your plan or something. There is no need to offload this work to your cellphone when the car has more physical space for that kind of thing anyway. I mean tesla's just have a borderline gaming computer in them these days.
