Do you have a Tesla? I do - and besides a native Apple Music app, I really don't miss Apple CarPlay at all
I have a Tesla (Model Y). I do miss CarPlay. I agree its not as essential as in pretty much any other car - but I still miss it.
I listen to podcasts on Overcast.
I prefer Apple Maps in many ways (and already have traffic there - an extra subscription in the Tesla).
I use other navigation apps for finding charging stations (the Tesla app can do this - but it's very limited).
I don't actually use Apple Music much while driving, but sometimes do (and the rest of the family do).
I usually have to run all these things on my iPhone, which I can at least keep on the induction charging stand under the dashboard screen - but it's hard to see the top of the screen without bending my head down - and is obviously smaller and more difficult to interact with safely.
I've considered one of the third-party integration hacks, but not taken the plunge yet!
If it was any other car it probably would have been a deal-breaker.
