I just wanted to post an idea I had to stop speeding in cars. Ok so when cars are moving they create air flow, under, and over them, and the faster they go the faster the air flows. Also because of flutes and whistles we know that when ir flows through holes of the correct size and placement it cretes sound. So what if perforated wires were run down the center of lanes with holes correctly placed so that when air at, say 65 mph, flows over it; it creates a high, anoying, whistle like sound. For this to work the holes would have to be cut in just the right size and distance apart but I believe it would be possible and could drasticly reduce speeding. Tell me what your think, thanks. Also I apolagize if this doesnt belong in this section of the forum, its the only one I could think to put it under.
