The American driver's response to a virtual frown would be a real middle finger.


We have them all over in Denmark. They work! - They're placed just before schools, and when you're entering small cities. They work for me, especially infront of schools. They're also good to calibrate the speedometer :-)

When i go 55 kmh on the speedometer, they usually say 50 kmh on the radarscreens.
