I don't think they need your permission to use ALPR on your publicly displayed license plate.

> (2) (A) “Personal information” does not include publicly available information [...]

> (B) (i) For purposes of this paragraph, “publicly available” means any of the following:

> (I) Information that is lawfully made available from federal, state, or local government records.

> (II) Information that a business has a reasonable basis to believe is lawfully made available to the general public by the consumer

The information being collected isn't your license plate, it's your location. (Still might not be personal information.)
