100% coverage seems like an inevitability in a country where filming in public is a constitutionally protected right and networked ALPR capability is possible (if not regularly offered yet) in commodity doorbell cameras.
> filming in public is a constitutionally protected right
As with everything, there's much nuance to this "right".

It is an inevitability, because a critical mass of municipalities are going to roll these out such that there isn't a practical route to take through any major metro without being recorded.
I'm a private citizen. On my house we have an ALPR Axis camera pointing down the street (in addition to Axis cameras around the whole perimiter.) And when the police ask, we almost always provide them with data. I feel perfectly justified doing this, and we've helped solved several crimes.

It really doesn't have to be though. The rights of individuals to record in public doesn't have to translate to the right of corporations (flock, amazon, etc.) to do it without restriction. Time, place, and manner restrictions on our rights already exist, it just needs to be found that this manner is unacceptable as an imposition on our freedom which should be protected under the fourth amendment.
