They don't seem very popular in the US, but always-on dashboard cameras already have obvious value. Maybe a dashboard cam cloud storage company could offer a discount on their services if you allowed license plate data to be gleaned from the footage you upload. Or maybe they would just throw a line in their ToS and do it.
