Beyond the fact that 70 people is not an acceptable survey amount (it's more like a margin of error), the statement above pretty much kills any credibility he or SA has.
CarPlay isn't fully baked yet, it fails at so many things that it's not something you would pay for separately—so you're sure as hell not going to pay top-dollar for the one or two models each manufacturer offers it in.
Saying it is "poised to handle the vast majority of consumers' needs" is about the same as saying "Blackberry phones are poised to serve the vast majority of mobile needs." Both statements are true... they COULD serve the majority of needs. But the reality is that they don't now, they won't tomorrow, and it's likely they never will.
Top that with the fact that Apple is stuck relying on car makers to actually put it in the vehicle to begin with (over their own self-serving option) and it's apparent to almost everyone (except for this guy, I guess) that CarPlay is going to be even less than a "hobby" than Apple TV is. The "majority of consumers" will never have a vehicle with CarPlay in it.
CarPlay (or Android's option) will "serve the vast majority of consumers' in-vehicle needs" when you're hard-pressed to find a new car available that DOESN'T offer it, not one that does.
If Apple could get GM, Ford, Toyota or Honda to commit to put CarPlay in EVERY vehicle they make starting tomorrow... that would change things. It would give Apple the leverage they need to eventually replace the horrible systems in the cars and completely take over car infotainment systems.
