I have a holder for my phone for when I use GPS and basically never interact with it directly after it’s set. Only real interactions are media controls via the steering wheel.
The only use cases I can see car play helping with are those who take a lot of calls/texts in their car while driving and those who listen to music and want to listen to specific songs.
Then the software side just makes the whole thing useless with a terrible UX that will never be updated.
CarPlay is a great solution because the non safety critical stuff (music, navigation) gets offloaded to a competent software company.
On my previous car it never changed from the day I bought it, other than navigation getting more and more out of date.
On my current car I get software updates occasionally. I’m not sure that function ever changed though.
Meanwhile my iPhone gets better every year. And if I buy a new phone? CarPlay can get faster. My car never will even if I wanted to pay them.
The ability to just get in your car and have the phone-powered interface right there without having to take your phone out of your pocket and mount it in the holder is something I didn’t ‘niceness’ of before experiencing it.
That car ended up sucking in other ways too. I quickly sold it and went back to buying old Lexuses. Wireless charging phone holder, and off you go. The siren call of infotainment is powerful, but actually living with it is just more fiddly bullshit I don't need in my life.
Honda is the worst. In two different Hondas, I had to make sure I didn't plug my phone into the blessed USB port to charge, otherwise the wireless AA connection would drop 20 minutes into the drive and I'd have to re-pair manually. And wireless would crap out every hour or so.
Mazda was wired-only, which was fine since my phone was new at the time. But Android Auto was clearly not designed for Mazda's otherwise very good non-touchscreen HMI.
Both Hyundai/Kias I've rented took a solid 90 seconds to pair every time I got in the car.
In a Chevy I rented, it would either pair up instantly and work perfectly or it wouldn't pair at all, depending on the alignment of the stars or something.
BMW's implementation worked great, too bad the rest of the controls in a modern BMW are idiotic. And also I can't afford one.
I've had several Toyota/Lexus loaner cars. Those worked fine, to my recollection.
Maybe I'm cursed, but at this point I don't particularly care. My real, honest-to-god experience with smartphone connectivity in cars is this: the most reliable, user-friendly, brand-agnostic experience is a bluetooth adapter shoved in the cigarette lighter, and a phone holder on the dash.
