There is a speed camera at a bridge in Venice, Italy. It may be that this is the fastest device in the world because it caught some supercars speeding at high speeds across the bridge.
Among the supercars were some sport cars, for example a £300,000 McLaren Mercedes SLR with a top speed of 200 mph. Also caught were some Lamborghinis, Porsches and Ferraris. It was at the cross-Europe Carbon Black rally.
Italian police hope they can track down the drivers.
