Probably not – not even downhill with a tailwind. But then why do many automobile speedometers have a display that shows the top-end at 160 mph? Turns out automakers want speedometers to be easy to read, so there’s value in placing the typical operating speed of American cars, 45 mph to 70 mph, near the top of the speedometer where it is easily read by the driver. To do this — while maintaining a visually-appealing, symmetrical speedometer — requires a gauge that displays well past operating speeds.  ….of course you may have an all digital display making this post rather obsolete.
