Same UI across all cars and one less thing of business creating an avenue / exit for your data. I get into a rental car, I connect my iPhone and use CarPlay, I don’t have to worry about leaving my contacts data behind or anything else, and I am already familiar with the UX. That is why Tesla and Rivian and GM don’t offer CarPlay, even though it is free and easy to implement. They don’t want people to be able to easily switch cars, they don’t want to just be a fungible appliance. But as a consumer, I do want them to be a fungible appliance.
