I have essentially gone with option 2 in my Audi A3. Every time I turn the car on, it puts up a dialog that warns me that I've made the terrible, terrible decision to not allow remote data and forces me to say, "no, do not turn it on for me now," before I can do anything else on the screen. Every, single, time.

This, but worse, happened with my inlaws when they purchased a new Lexus (IIRC, a 2025 RX350). It has whatever kind of built in navigation & traffic feature but they wanted to use Android Auto. You can do that, but not until after you go through Lexus' vehicle/driver registration process to enable their built in system. If you don't, not only will neither AA nor CarPlay work, but if you try to use the built in nav it will fail with a superimposed modal after a couple of minutes to nag you into creating an account.

Disappointing but not surprising. Those touchscreen interfaces are usually full of nags. I liked the Versa I rented recently cause its "low-end" radio system was the only thing that let me listen to the damn radio without jumping through hoops. Toyota's is an L even though their cars are better otherwise.
