It’s a partial driver, perhaps even meaningful in some way, but this is hardly an A/B test. Suffice to say lack of CarPlay is costing them in some way but model refreshes, steep price discounts, and other economical considerations are going to win out. Sure, 79% of some sample of car buyers said they wouldn’t buy a car without carplay but putting carplay in an otherwise crappy car isn’t going to magically make people buy that instead. There’s a lot of reasons Chevy is struggling. Blowing their own foot off with this decision can’t have been good for business but it’s certainly been hilarious for the quotes their execs have had to say in public with straight faces so they don’t get whacked for not following the party line. At some point I’m sure there will be a reorg where the opposite will become true.
