I remember the association of my old neighborhood complained abuot excessive speed, so they put one of those up on the end of the road. So, hey, my friends and I put it to good use. We took out our R/C cars and ran 'em. I was kinda surprised that the thing did pick 'em up, but hey, it was cool anywayz.
