What if someone were to devise a mechanism to detect and prosecute people changing lanes without indicating, with the following properties?

- perfect accuracy (no FP; no FN)

- automated enforcement via a fine, without knowing the identity of the perpetrator (just assume it's possible; I know it's hard)

- no potential for the device or underlying technology to be used or repurposed for any other form of surveillance or enforcement

Would such a system (and automated enforcement) be OK?
