A lot of state departments of highway/transport already do this. You can even access the video streams online, intentionally. Just check your state, there's probably a lot of traffic cameras you can access. These are often used for traffic analysis like identifying and fixing congestion, accidents, etc. It's not too different than you setting up a higher res camera from your home or yard and doing the same. Some states have protection laws on cameras setup for these purposes that the data cannot be used as evidence for criminal acts IIRC. For example, many traffic lights have cameras to adjust patterns as needed. It's not a huge step to then turn all of them into red light cameras the record running violations. It's a bit more complex for other violations but you get the idea. I'm surprised private entities haven't already tried using this public data to associate license plates with cars, perhaps attempt to detect dangerous driving behaviors, and sell that to insurance companies to adjust the rates. There's so much surveillance data that could be mined in largely harmful ways to the general population at large and I think it's only a matter of time before businesses start doing more of this type of work as soon as they see value and a population complacent enough to take yet another attack on them. Car insurance companies seem like they'd be interested in traffic video they can associate with license plates and improve risk assessment on their customers. Not sure what, if any, consumer protections exist to prevent this right now. It's probably just cost prohibitive currently.
