Well that is nice to know that you're being critical because you're interested in buying one. Mange just bought a car and isn't in the market.
I will not deny there are people out there just champing at the bit (chomping?) for this tech but I do question your assertion that it is most people? Yea, I don't think it's "most people". Most average people buying these grocery getters probably aren't even aware of what Apple Car Play even IS until the delaer sits them in the CR-V and says "Check this feature out".
As I've said I am THE tech guy in my circle of humans. EVERYONE asks me for advice about everything. None of them are talking about this stuff. Friend just bought a new car that has AA - she didn't even know it had it when I mentioned it to her.
It's obviously a deal breaker for you, so you should remove the CX-5 from your short list.
