This would have worked in trustworthy societies - not these ones. (If a trustworthy society is still known in these times, please inform.)
And robot vacuum cleaners :) Although there's some hostility to cybershow here I'll reference a couple of episodes because surveillance is a frequent talking point. In this [0] one the discussion is exactly what you're talking about.. cars, and the incident with Tesla employees sharing 'funny' road traffic accidents.
In this other discussion about CCTV in general [1] two notable things came up:
1) From a security POV, there's an impotency of digital surveillance. It is a tool that works well as post-facto analysis (such as arresting a bunch of rioters the next day). But it has less value in real time unless you also have human resources - and in most cases (except in dangerous war zone) if you already have them they're superior to any electronics.
2) Communities are sold surveillance by an "insecurity industry". It's a big business. But they rarely reflect on its value or other effects. Surveillance is a sign of poverty if you take all quality of life factors into account. Overt security signals inner insecurity and social decay. The more cameras you can see in a place the 'poorer' that neighbourhood since a truly wealthy society is one with high trust.
(Not wishing to be pedantic for its own sake, there's an important distinction)
High-trust is the average trust metric between any two randomly chosen individuals from the set at some time.
Trustworthiness (in one regard) is the historically accumulated record of positive performance against promises made. But a society is not a single entity. Maybe society's representatives might be trustworthy.
So there's a push for "zero trust" society. What do you make of that?
Given that what happens is what is allowed by the society in which it happens,
the priority is to flee - as fully bad indicators are there. The problem remains, "to where" - identifying a society that still recognizes and defends Dignity.
While the concept of privacy makes it into laws, it's still just a minor component of a broader "dignity" that so many technologies seem set on destroying. A dozen or more major thinkers since the 1900s have noticed that human dignity is very fragile in the face of technology (Weber, Marx, Fromm, Freud, Jung, Nietzsche...) Surveillance is just one modern facet of undignified life with technology.
Question: can technology ever enhance dignity?
We've seemingly built a system (society) in which material and social success hinge on a willingness to forgo dignity. People who have a strong sense of dignity are disadvantaged and marginalised. So to answer your "to where?" To the margins. Unless one is prepared to embrace indignity in visible opposition. Struggle may be the last refuge of dignity.
According to what would-be objective judgement? Under a threshold you fight; over a threshold you flee. It is just sensible. Dignity may or may not be impacted, heightened or lowered - it depends on details.
> can technology ever enhance dignity
Of course tools and devices are meant to enhance dignity, we build them for a purpose - to serve us and assist.
> We've seemingly built a system (society) in which material and social success hinge on a willingness to forgo dignity. People who have a strong sense of dignity are disadvantaged and marginalised
Very correct. (Careful with those «we».)
> To the margins
Of what is not your society? Look at reality. It is a procustean coexistence of squirrels and Men. There will probably be societies less vile.
