Automatic license plate readers (ALPRs) are nothing new, but reported abuses have made drivers understandably wary of the cameras made by Flock and other companies, to the point of wanting to find out where they are so they can be avoided. While that added attention has made intersection cameras seem more visible than ever, not every camera you see mounted above the road serves the same purpose. Most cameras on roadways aren't used to track individual drivers, but rather to monitor traffic conditions.
