> Musk tweeting about whether or not the driver purchased certain features is insane. He shouldn't have access to that data, let alone be allowed to publicize the information.

I agree with you up to this phrase. A company knows exactly what you purchased from them, so knowing what a certain customer bought is just a call away, and not only for the CEO.

Regarding publicizing if you bought a certain feature or not, I think withholding that information when the media, and even the police, were blaming the non-existent feature for the accident, is more than you could ask of most of us.

Choosing between risking a fine for divulging shopping data, or a costly and unfair reputation hit while the police investigates. The decision seems obvious.
