I'm not surprised. $10 a month about an album a month purchased but grants access to a much wider catalog. I'd like to see Apple find a way to straddle the bridge between those that occasionally like to own the music versus rent.
I still think it's likely that Apple and Tesla come to an agreement but until that happens or not Apple's going to plumb the well and see what they come up with.
I see little animosity with Tesla as the landscape really is competing with incumbent auto manufacturers who aren't sitting on their hands wrt to ICE vs EV.
That would be an interesting legal battle because Touch ID and other biometrics don't absolve passwords they just add another layer of authentication much like a keyboard is generally required to input said password.
