> There should be absolutely no expectation of privacy when using public streets.

Strong disagree. Life in public areas is often still part of private life. And we should treat it with the respect and privacy that it deserves. You going to the doctor? That's part of your private life. You meeting with an old friend to catch up? Also private, even though you do it in a public cafe.

In the USA? Any café you go to is reasonably likely to have cameras, both inside and outside. If you mean driving to a doctor's office, you probably pass by hundreds of cameras along the way: video doorbells, dash cams, Teslas, Waymos, gas stations, ATMs, traffic-flow cameras, etc. If you are in one of the many cities with tens of thousands of existing non-Flock cameras, you are likely passing many more.

I also disagree with OP.

It seems like (to my very uneducated mind) the founders were worried about the tyranny of government. We have the bill of rights and a constitution designed to limit government powers.

But then there are people who weaponize rights against the people in favor of the government.

A private company creating a mass-surveillance network of tracking everyone in public is absolutely a weaponization of rights. Rights designed to keep our government accountable. Our rights that give us tools to prevent government from weaponizing privacy against us (secret juries, secret trials, secret government employees, records etc citing 'privacy' as a reason for secrecy).
