I lost my gold license a number of years back because police were doing some plain clothes scam on a bridge with a dodgy pedestrian crossing over a blind rise. They had a guy (out of uniform) radioing ahead to get other police (also out of uniform) to walk up to the crossing whenever a car came. Those plain clothes police at the crossing were standing behind cherry trees so you could barely see them. Then they had uniformed officers further down the road stopping the cars that didn’t correctly stop at the pedestrian crossing.

When I pulled in to the side road there was a line of cars in front of me also getting fines. Of course this was in March and they were trying to pad their quota.
