This feels like too far the other direction. I am of the opinion that the following are all reasonable, and I think most people would agree with me:* Toll enforcement (the only thing allowed by the law)
* Speeding enforcement
* Parking enforcement
* Real-time alerting for vehicles that could be pulled over if you knew nothing other than the vehicle's identity. Stolen, unregistered, uninsured, amber-alert, etc. [1]
I think the following are all unreasonable, and I think most people would agree with me:
* Selling the data for any commercial purposes (perhaps with the exception of aggregated statistical data)
* Mining the data "suspicious patterns of activity".
I think the following is reasonable, but some people may disagree:
* Retaining the data for a limited time, so that if a crime is reported involving a specific vehicle, you can look back for sightings of the vehicle contemporaneous with the crime to help catch the bad guys.
Given my thoughts on what is and is not reasonable, I think the ideal policy is one that focuses on limiting retention, limiting sharing, and limiting the types of queries that can be performed on the data. Something like:
* Can retain the data for 90 days. Data that is evidence of a specific crime can be kept longer with the evidence file for that crime, and destroyed when the investigation is done.
* Can use the data where knowing a series of (time, place) pairs for a vehicle is probable cause of an infraction (or toll due). This covers speeding and parking and tools and red lights and registration/etc, but doesn't allow looking for suspicious patterns of activity.
* Can query the data for sightings of a specific vehicle with reasonable suspicion that the vehicle was involved in a crime. Need to keep records of these queries to identify abuse. Maybe need to notify owner when such a query is made.
* Can not disclose the data to third parties, except in the case when they agree to follow all these same rules (so you can share with other departments or law enforcement service providers, but that doesn't enable an end-run around the rules)
[1]: And I think it's important here that if data about a vehicle be eligible to be pulled over knowing nothing but it's license plate is out of date or otherwise wrong, then someone gets in serious trouble. Otherwise nobody is incentivized to keep their database up to date.

> I am of the opinion that the following are all reasonableI'm not. Tolls are fine since the "enforcement" there is of a known cost that you have to pay to use the road.
But I don't think speeding laws, or indeed any traffic laws that allow people to be fined or punished just because they broke some administrative rule, should exist at all as they exist now, let alone be enforced by automated cameras.
Even with cameras, it's obvious to anyone who drives that such laws are not even close to being actually enforceable as they're written. Raise your hand if you've gone faster than the posted speed limit on a US road, along with probably 95 percent or so of all the other cars on that road. Raise your other hand if you've not come to a complete stop at a stop sign because you can see that there are no other cars coming. And so on.
Such laws should not exist because "enforcement" becomes an arms race between the police and the citizen. It would be better to get rid of them and make things like speed limit signs, etc., advisory--you can't be ticketed just for not obeying them, but if you get in an accident and it's found that you weren't obeying a sign, you're presumed to be at fault. Then this whole issue would evaporate. The cameras could still be there--and their footage would be admissible evidence in any dispute about an actual accident. But they couldn't just trigger an automated ticket to be sent to you if no accident took place.
