I admire JFP's tenacity in warning us of the 'ticket bait' problem.
I have this device on 2 cars and we use them on the awful Los Angels freeways where the driver behind you during a panic stop is usually on Facebook. Hopefully CHP have better things to do than ticket someone who makes an effort to save their own life and the fool on Facebook behind them. Sometimes "the law is an ass". Example - we now have legislation to allow cyclists to blow through Stop Signs ! Hopefully they carry Organ Donor Cards.
