Check your speed

This morning it was quite funny when I came across this speed detector, which was recently put up and is of a temporary nature.  I tried to get someone going in excess of 30mph to show the unhappy face.  But drivers saw me with a camera and slowed down in every case.  Later at a distance I noticed that most drivers just ignored the speed detector.

I will try again, but next time I will select a slow shutter speed to get vehicle motion.
