I think what you're trying to say is cars will start identifying folks and logging their location. Cell tracking/triangulation data is already available from cell companies. Self driving cars aren't going to make things worse.

Optimistic to think that having more ways to track people won't make things worse.

Carrying a mobile phone is optional.

And visual detection more precise. You can tell not only if someone is usually within a few tens of metres as you can with cellphone data, but exactly where they are, what they're doing, and who/what they're looking at.
