One of the most common uses of this tech in the US is automatic license plate readers. Without getting into a debate about expectations of privacy on public roads vs. building a perpetual government database that tracks where every car is effectively at all times of day, another application of this tech would be a bumper decal. I think most reasonable people would agree obscuring the license plate on a public road is not the solution (well, with the exception of Florida Man who racked up a $1MM fine when he was finally caught doing that through toll booths for a year), but a decal like this wouldn't interfere with any officer's human duties.
