My car has Android Automotive and CarPlay and Android Auto are disabled. Honestly, if I was driving my car for all days, eight hours a day, the Android Automotive is better. However, I don't. I drive for a few minutes to work on days when it's not safe to ride my bike. That doesn't happen very often, but once in a while. It's just not worth the monthly fee and I'm really frustrated the few times I do get in my car that I can't use my phone because a car keeps jumping in when I say, hey Google. if I'm using maps, I don't see the friendly display. Which direction I'm supposed to turn and so if the kids are talking to me at the same time the jumps up, I sometimes miss my turn indicator. When playing music I don't have a nice convenient touch in front of me to say skip this song instead I have to pick up my phone which of course is illegal now for good reason.

Worth noting that with some brands when the free cellular service for the car's use runs out and you would need to start paying you can go to the network settings and tell it to use an external WiFi network, such as your phone's hotspot, instead of the built in cellular connection.

Also, my phone follows me between vehicles and provides the exact same interface in all of them. Heck, I can switch vehicles and my podcast or music starts back up right where I left it. That alone is a major win for the phone-based approach - if I drive my spouse's vehicle for instance, or my old truck because I need to haul something, doesn't matter, they all have the same navigation and audio.
