In my experience, people don't adjust their speed for passing based on the speedometer, they do it intuitively. I would however like one that could make, oh say... ... a happy face, a sad face, and a raised middle finger, for communicating with motorist. :-) :-( -nImhowajoSun, 24 Aug 2008 16:07:11 -0000http://www.ohgizmo.com/2008/08/21/speed-vest-shows-bikers-current-mph/#comment-1767927I would guess that showing your speed on a bike lets drivers behind you know how fast (or slow) you are traveling and gives the driver a little bit more information for safely passing the cyclists. Thus creating a safer drive for both.Greg LeMondThu, 21 Aug 2008 20:00:53 -0000
