Since you use Spotify It works fine for you. But what about people who use a different service? For example, I use Apple Music. Tesla is an awful experience, to people like me, because they don’t work with my chosen services.Just my opinion, but I enjoy my tesla without CarPlay vs my wife's Yukon with CarPlay. the Yukon is getting the boot once the R1S arrives. While I miss Waze in the Tesla primarily, they've integrated Spotify well at this point. An update last year made a big improvement from their first attempt. OTA updates are so critical for Rivian to work out the inventible bugs in the UI.
CarPlay is a solution that delivers customers choice and high quality, while being easy for the auto manufacturers to implement.
