The latest neat idea in GPS devices has apparently struck a sour tone in Switzerland: the Swiss highway department has issued an order banning any GPS unit with the ability to warn a driver of the presence of nearby automated traffic enforcement systems (speed or traffic light cameras). Police may now stop drivers and examine their GPS units, and if they find one with such capabilities, confiscate and/or destroy it. The same law also makes a long list of devices illegal to sell in Switzerland.
In Chicago, the city is required to put up signs warning people that the intersection they're approaching is protected by a traffic camera. The GPS device would be redundant. I don't understand why the Swiss are so knotted up over this.
