991.2: CarPlay In, Android Auto Out
From 13 Cool Facts About the 2017 Porsche 911 on Motor Trend
5. The new 911 Only Has Apple Car Play Because Google Is Nicht Gut
So much for "Do No Evil." There's no technological reason the 991/2 doesn't have Android Auto playing through its massively upgraded PCM system. But there is an ethical one. As part of the agreement an automaker would have to enter with Google, certain pieces of data must be collected and mailed back to Mountain View, California. Stuff like vehicle speed, throttle position, coolant and oil temp, engine revs—basically Google wants a complete OBD2 dump whenever someone activates Android Auto. Not kosher, says Porsche. Obviously, this is "off the record," but Porsche feels info like that is the secret sauce that makes its cars special. Moreover, giving such data to a multi-billion dollar corporation that's actively building a car, well, that ain't good, either. Apple, by way of stark contrast, only wants to know if the car is moving while Apple Play is in use. Makes you wonder about all the other OEMs who have agreed to Google's requests/demands, no?
Kudos to Porsche for taking a stand in support of privacy, even if they may have an ulterior motive -- i.e., they don't want Google to gather all that basic data on how their cars operate.
Although it at least appears that if you don't activate Android Auto, Google won't get this data from your car (from manufacturers who are including both), Google has a history of "inadvertently" collecting data they aren't supposed to collect. So, not including it at all is the right choice, because while some might want the choice to use it, others might not want the choice to not be spied on and tracked in the physical world "inadvertently" taken away from them by a company that has proven it can't be trusted on privacy issues.
Porsche obviously, and rightly, views Android Auto as the Trojan Horse that it is.
