Carmaker Porsche has chosen to go with Apple's CarPlay and will not support Android in its 2017 car models.
Google apparently wanted a complete and constant data dump from every car, all the time. Apple was not making that kind of requirement in its CarPlay licensing.
As Internet-based technology matures, I am glad to see that some companies are recognizing that privacy is still more important than technology. Kudos to Apple and Porsche for respecting their customers.
