A Gatso camera in Cardiff that cost £20,000 to install has snapped just one speeding driver in an entire year, returning a £60 fine.
Arguably that means the camera has been a big fat road safety success, because there are evidently no drivers speeding in the area.
However, enraged local residents quoted in The Daily Mail say the camera is a "joke" that "does nothing to improve road safety."
Big Brother Watch doesn't like it much either, calling it "an example of excessive surveillance invading our lives under the guise of safety." There's been no word from the solitary driver who was flashed in 2009.
The camera, which is placed on a street in Rhiwbina Hill, has a considerably easier job than Cardiff's busiest fixed camera, on the M4. It flashes 18 drivers per day on average, collecting over £1,000 for its troubles.
Rhiwbina Hill residents argue that excessive speed was never an issue on the road, and are baffled as to why it was put up in the first place.
Local councillor Adrian Robson agrees: "Historically there were a few accidents caused by the low sun blinding cars as they came over the hill," he said, "but if the average speed was lower than the limit, then speed wasn't the problem."
