BERLIN When Marc Guerin, a software salesman, drives the 38 kilometers from his home west of Paris to Roissy Charles de Gaulle Airport, he seeks out the fastest route for his Audi Q5 crossover and powers up his Coyote, a radar warning and traffic service that alerts him to the locations of Frances 3,000 speed cameras.
When Mr. Guerin comes within four kilometers, or two and a half miles, of a speed camera, his Coyote screen warns that he has entered a risk zone, and he closely monitors his speed.
Since he began using Coyote three years ago, Mr. Guerin said, he has not received a speeding ticket. He said he used to average three or four tickets a year which cost him about 400, or about $515.
For one thing, I no longer get caught by the speed cameras, which are all over France, Mr. Guerin said. For another, it advises me constantly of the legal speed limits and traffic conditions, so I am better informed and much more relaxed when driving.
