Today, the Mozilla Foundation published its analysis of how well automakers handle the privacy of data collected by their connected cars, and the results will be unlikely to surprise any regular reader of Ars Technica. The researchers were horrified by their findings , stating that "cars are the worst product category we have ever reviewed for privacy."

Mozilla looked at 25 car brands and found that all of them collected too much personal data, and from multiple sources—monitoring not just which buttons you push or what you do in any of the infotainment system's apps but also data from other sources like satellite radio or third-party maps. Or even when you connect your phone—remember that prompt asking you if you wanted to share all your contacts and notes with your car when you connected it via Bluetooth?

While some gathered data seems innocuous or even helpful—feedback to improve cabin ergonomics and UIs, for example—some data is decidedly not.

A long while back, Toyota told me it didn't want to give up interior real estate to Apple’s CarPlay. The automaker felt that losing that space to the tech company would be a huge mistake. Fast forward a few years, and after what I assume were some internal struggles, it caved and now you can get CarPlay and Android Auto on your fancy new Highlander, Prius, Tacoma, or Camry. It seemed like a silly decision had been reversed. Now it’s GM’s turn to go down the same path.

Today, news dropped that GM would be phasing out CarPlay support in future EVs . In its partnership with Google, it hopes that all the features you get from mirroring your iPhone can be replaced with an Android Automotive feature . GM, like Toyota before it, wants to control the digital real estate in its vehicles. It’s a revenue-based and walled-garden (ironically against Apple) decision that will cost them.

Software-driven vehicles should be about choice. Instead, GM is making a short-sighted decision based on a trickle of revenue under the guise of better integration. Owning all the data that a vehicle generates while driving around could be a great source of cash. The problem is potential customers have become accustomed to choosing which device they use to navigate, chat, text, and rock out within their vehicle. They’ve grown weary of being mined for data at the expense of their choice and they’re really not all that keen on in-car subscription services .

In surprising car news today, we've learned that General Motors is planning to drop support for both Apple CarPlay and Android Auto from new electric vehicles it plans to launch in the next few years. The decision won't affect any GM vehicles already on the market, nor will it apply to gasoline- or diesel-powered GM vehicles in the coming years—just EVs.

"As we scale our EVs and launch our Ultifi software platform, we can do more than ever before with in-vehicle technologies and over-the-air updates. All of this is allowing us to constantly improve the customer experience we can offer across our brands," said Edward Kummer, GM's chief digital officer.

GM told Ars that it's moving away from phone projection to offer customers a more integrated solution that sees Google Maps, Google Assistant, Audible, Spotify, and other applications run natively on its cars' infotainment systems.
