Here in the U.S., we spend gazillions of dollars on cops and radars and helicopters and speed traps--all in the name of speed enforcement. (Either that, or it's all for revenue.)
Leave it to the Danes to give us the absolute best, most effective--and low-cost--solution to reducing drivers exceeding the speed limit.
Works for me. What with all the girls we have running around looking to "bare themselves," why not pay them a little bit and give them a sign?
Then we could let our cops get some real work done chasing real criminals--like our politicians.
