I view your response as perhaps a bit disingenuous
I'm not sure that word means what you think it means.
As an example of there's always gonna be people unhappy there's threads on here from when they added Spotify- a quite popular service- with lots of people complaining they didn't add INSERTWHATEVERONETHEYLIKEHERE.
Including some I'd never heard of.
since just about every new car for the last several years has offered SXM; when it comes to auto audio that’s not bog-standard AM/FM, SXM is probably the most widely available, not a niche choice as you imply.
I didn't imply it was a niche at all.
Since you mention it though SXM has about 34 million users.... Tunein (available on Tesla!) has 2-3 times that many users. Spotify has over 400 million users.
So comparatively, SXM IS kinda niche
Anyway- I wasn't really implying anything- instead I outright stated there's always going to be SOME service someone wishes they'd add, and until they go app store it doesn't make sense for them to offer a bunch of them through their own internal development efforts.
Not to mention most peoples complaint when you point out you can just stream SXM from your phone is to whine BUT WHAT IF I DO NOT HAVE SIGNAL.
Which of course would mean simply adding an app won't help them.
Tesla would need to add actual SXM hardware. Which costs money. Not just the single cost in a single car- but cost in manufacturing complexity, supply chain complexity, service and engineering complexity, support cost, licensing deals with SXM, etc...
If you know anything about how Tesla thinks and operates, that's the opposite of something they'd be interested in for their mass market models they're gonna be making millions of a year.
So brings us back to your choices today are:
Use the phone app and stream over BT
Use some aftermarket kludge to add an input for a tuner and control it somehow
Wait for a native app- which may require waiting for an official app store to launch
Note only the middle one has any chance of helping if you're in the "I want it so I can listen in places without cell signal" camp.
