> What about telemetry for self-driving cars?

They own the cars so they can track them all they want.

Tracking me all over the place after I click the "Do Not Track Me" button isn't acceptable.

It quite could be. Just as we humans decided to not use the scientific research generated by the Nazis on unwilling human subjects there are definite limits to what is acceptable even if the overall benefits are huge.

Collectively, we did no such thing. Many individual researchers and journals refused to use Nazi research, but many felt that it was unethical not to use it if it could save lives. In particular, I believe that the results of Nazi hypeothermia experiments were extensively used after the war. It's certainly not a cut-and-dry problem with an obvious ethical answer.
