I was at a tech conference recently, and the local city tech department was showing off the cameras all around the city. They were all tracking individual vehicles with computer vision, across town as the traffic moved from one camera to another.

I didn’t get a chance to ask them whether law enforcement used the data, but I’m pretty sure that’s a given.

Same here, but apparently this isn’t even an isolated example:
