I have a ‘21 Miata with the same gripes. The CarPlay situation got slightly better with an OS upgrade last year – now it only crashes about 10% of the time, and 75% of those recover on their own without needing a power-cycle.

The lack of adaptive cruise is baffling. We test drove a ‘15 CX-something-or-other in 2014 and it had the ability to brake automatically (dealer was very interested in demoing this feature). I assume it also had adaptive cruise, so it’s wild that a 6 years newer sports car wouldn’t have that feature.
