No problem, that's why they invented Stingrays and license plate cameras. This stuff is all over the country.

how does that work with speed cameras?

Traffic cameras can read and track license plate numbers, how is that private?

Cars are amongst the easiest of things to track - cameras with license plate recognition, and potentially with the capability to also photograph the driver are widely deployed, in many places in Europe; I don't know about the US. With an infra-red flash, you'll not necessarily know you were photographed.

My understanding is that the only thing keeping this from happening is that the data is far more valuable for traffic monitoring than law enforcement. As a trivial example, these cameras can already determine is a vehicle is speeding based on its number plate sightings between any two cameras. They can hence start issuing tickets, no radar or police needed.However, they've not gone down this path because they are (rightfully) concerned that there would be an instantaneous and severe back

Doesn't the UK have cameras everywhere doing this anyways?

We have automated pictures/registration and ticketing for cars that blow past a red light or somewhere else a camera is installed, if you have enough of them nobody speeds anywhere (without punishment)

Automated speed cameras that issue fines/penalty points based on your number plate? Those are a thing in many countries.

If you have a license plate, then its being tracked with cameras when you use it.

it would be cool to crowdsource police traffic enforcement locations automatically from phones mounted to dashboards
