IMHO, 40 days is too long. The data should exist for as long as the investigation occurs. With plate scanners, that should be measured in seconds. While I disagree with plate scanning in general (people should be held to their driving habits, not their registration practices...) Holding on to that data for longer is just assuming that everyone is guilty of something and until you out what, you retain that data.
