I agree. That's why it doesn't make sense that Tesla is approaching it as "bespoke or bust".
> Bluetooth audio is a thing, and you can stream whatever audio you want from your phone to your car audio using that.
Yes, but "streaming a single audio track (with low audio quality)" is pretty much all BlueTooth is fit for, and the problem is much larger than that--a luxury car should be able to stream higher quality audio and it should also be able to stream video (e.g., HBO, Paramount Plus, etc). Moreover, it should facilitate a media browsing experience through the touch screen. First of all, it's limited to audio--it doesn't help me stream HBO or Paramount or any other video service.
Apple and I believe Google are very strict about which apps can be used for CarPlay/Android Auto. There would be major repercussions if they weren’t.
Tesla has apps for a bunch of video streaming services. And for those it doesn't have, you can just use the built-in web browser. It works just fine (assuming you are in a parked mode, they won't work while you are driving for obvious safety reasons).
