Eh.. I get rental cars regularly right now.. cause you know, no Model X for 354 days now, and they've always had CarPlay, and wireless CarPlay. Candidly, I sorely miss my M3 interface..
Apple Maps is not good in my area, Google Maps continues to seem glitchy and sometimes will show the step by step on the phone, but not show the map on the car. I use Spotify and Apple Music, so I do like Apple Music integration, but will give Tidal a shot once my car finally arrives.
And for the roughly 40% of Americans without an iPhone, that doesn't necessarily help to just have CarPlay without Android Auto..
