In theory, 2 BiB in the car can "do you" on their opinion alone, they don't need any measuring device at all.
But it doesn't happen that way, if you were going fast enough to attract their attention they would come after you.
yep, had it happen to me a few years back. the Bib in question were waiting to turn right at traffic lights that i went through in the opposite direction. i had to stop at further traffic lights just down the road - they did a u turn and pulled me. I got a telling off rather than a ticket and drove slowly for some time after....
