Well I'm glad that one sales guy at a franchised dealership seems to know the inner workings at GM to know that information. Google it, there's no mention of that whatsoever and this is the problem. You're simply stating what you heard from one person or your own personal opinion as fact when you've got no data to back it up. Here some info
- Consumer Demand: A 2022 survey indicated that 79% of U.S. buyers would only purchase a car if it supported Apple CarPlay.
- Purchasing Factor: Roughly 23% of new car buyers consider CarPlay a "must-have," while 56% are interested in having it, according to a Strategy Analytics study.
- Preventing Sales Loss: Car manufacturers that lack Apple CarPlay (or Android Auto) risk losing customers, with 14% of consumers stating they would switch brands if their preferred, phone-like interface was not included.
- Industry Adoption: Even brands that previously resisted, such as Tesla, have looked into adding Apple CarPlay to boost flagging sales.
- Value Retention: The presence of Apple CarPlay can increase a vehicle's resale value, as buyers seek modern, integrated technology.
So while 79% say they would only purchase a car with CarPlay only 23% of that group say it's a MUST HAVE and actually may follow though. This is a prime example of what people say vs what people do are two very different things. The only reason Tesla is considering adding it as they're throwing everything at the wall to see what sticks in order to get sales back up, who knows if adding it will give them a small, medium or large boost in sales (I'm predicting small).
Clearly some people do see it as a dealbreaker (you included) but let's not skew the facts and say that Automakers are going to lose a tonne of sales dropping or not offering it when there's no strong evidence to back it up. Hearsay is not a valid argument.
