In some states you no longer can interact with a phone at all unless mounted. Phone mounts kind of suck or you’ll be in a rental without your nice mount. A 15” screen is easier to read than a small phone bouncing on a mount.

If I’m spending $10K on something, I want the Android/iOS experience to be first-class instead of some shitty UI designed be people who I presume don’t drive cars.

Cars are otherwise fungible between brands. If one has CarPlay/Android Auto there is little reason to pick a brand that lacks support.

I recently upgraded to a car with CarPlay, and it's actually a worse user experience than just having my phone on a really solid Brodit phone holder.

For example - when using Google Maps on my phone I can pan around the map to look at nearby places really quickly - maybe while I'm stopped at traffic lights, and then reset back to the navigation. Spotify in CarPlay is really hard to use - much harder than the normal app. Whether it plays the song you want seems to be a game of chance.
