It's a shame then that the few laws we have protecting consumer's privacy are not adequate to the task. It's reasonable then to do our best to avoid products and services that exploit the weakness of our laws until that situation is improved.

As an aside, how do you know that the apps you use aren't selling your data? Is it only because of their entirely non-legally binding statements and privacy polices? What do think could happen to that data when those apps/companies are sold or otherwise acquired by someone else? Even if they were telling the truth about not selling your data right now, do you think that means it isn't readily available to police or the discovery process in a legal dispute? Do you think that data collected or displayed by the apps could be exposed to Google or Apple and collected?

The real bonus is that it appears as if this update will help isolate the app from the vehicle. What I mean is that the current way these apps work is they poll the vehicle for data. This is bad because it (potentially) wakes up with vehicle and increases battery consumption. The way I understand it, this new method will allow apps to "poll" Tesla instead, which is a much better operation.
