One is a system called DriverFocus that monitors the drivers face, runs some sort of facial recognition software, and alerts anytime it doesn't think the driver's face is paying enough attention. Unsurprisingly it's horribly buggy and has a ton of false positives, but even worse: you can't disable it! There's a setting in the menu that will turn it off for that trip, but it will turn itself back on during a future start.
To make it even worse, some models can't be purchased without it now. I can only imagine what the company will be doing with that facial data down the line. I absolutely don't want a car that constantly spies on my face in a way that can't even be turned off.
Between that feature, this telemetry article, and some other anti-user features it's incredible what a customer hostile company Subaru has become. It's a shame because they used to be one of my favorites.
