Why does it only work "when cars are traveling at exactly 45 mph"? Wouldn't any constant speed work? You would simply play the song in a different key depending on the speed, like changing the speed of a record player.
- elsurudo 11y agoYeah but at most speeds, it would probably sound like an out-of-tune instrument
- bnegreve 11y agoThere are many variables that do not vary linearly with the speed (e.g. rubber's stiffness) so it could be that the sound is indistinguishable at higher speed. The goal is clearly to slow people down, so that would be really surprising if it would work the same way at higher speed, wouldn't it be? Maybe I'm just too naive..
