Honestly, it's a far superior approach for European car makers than developing subpar software, pouring millions into it, and marketing it as a grand design while failing to get even the basics right.
Strategically, for Volkswagen, it's crucial to test and consider using Android Automotive as an alternative to their proprietary software to remain competitive.
Laughs hysterically in Google. Oh my God, I'm going to have cramps.
What would Google possibly want with massive data dumps from people buying new porsches??
The data gathered by a smart phone is limited to what you do on the smart phone.
The data available via CANBUS isn't something that is available basically anywhere else, and has the benefit of probably half a dozen cameras pointed at you, and your garage and house, and every person you drive by on the street and every place you go. They could determine if you saw a billboard on your drive to work. They could ID you walking into an abortion clinic across state lines or hear you picking up your prescription at the pharmacy.
Your car (especially one marketed with 'smart' features) is basically a giant collection of sensors and cameras. I'm not saying that it's worse, but adding all that data in with all your other data certainly IS worse.
