I'm pretty sure there is no reasonable expectation of privacy while "walking down the street" anyway?

There's a substantial difference between:

- I walk down the street and everybody can see me.

And

- I walk down the street and my moves are recorded and stored forever in some db which may be abused or leak.

The chances of that piece of information coming back to hurt you in the course of the next decades are so much higher.
