> Not to mention the likely need for continuous internet connectivity and service upkeep. Car companies aren't exactly known for good software governance.

I don't own a car but rent them occasionally on vacation in every one I've rented that I can remember since they started having the big touch screens that connect with your phone, the voice button on the steering wheel would just launch Siri (on CarPlay), which seems optimal—just have the phone software deal with it because the car companies are bad at software.

It seems to work fine for changing music when there's no passenger to do that, subject to only the usual limitations with Siri sucking—but I don't expect a car company to do better, and honestly the worst case I've can remember with music is that played the title track of an album rather than the album, which is admittedly ambiguous. Now I just say explicitly "play the album 'foo' by 'bar' on Spotify" and it works. It's definitely a lot safer than fumbling around with the touchscreen (and Spotify's CarPlay app is very limited for browsing anyways, for safety I assume but then my partner can't browse music either, which would be fine) or trying to juggle CDs back in the day.
