IMO cars that have their own infotainment system should also allow Android Auto and Apple CarPlay. Give the user a choice. Collect metrics about how many people use Android Auto / CarPlay vs the native infotainment system. Maybe survey people who use Android Auto or CarPlay often to see what they think is missing from the native infotainment system. Iterate. Get people to use the native infotainment because it’s better, not because you force them to.

I’ve got a BMW iX and the in-built map is very good, but I like knowing that I can switch to Android Auto if I encounter issues with it.
