Speed trap - Euston underpass Fri lunchtime

Spotted the sneaky rascal this lunchtime on the central reservation opposite Gower Street, clocking eastbound traffic using a handheld.
He is doing it correctly by “forming a prior opinion” rather than just prospecting everything that moves.
There’s a traffic car some yards down the road towards Euston station which is tugging transgressors.
Wasn’t getting much action from what I observed as traffic to heavy. But watch out chaps and chapesses.

thanks, on my way through there soon
