Ted Miller, editorial board member and famed for much else, kindly sent a link to an excellent youtube video that I urge you to watch. I do so because I have long cautioned that pedestrian signals can be dangerous if you assume that cars will always respect them. I plead with my friends, family, and former patients (I am now retired) to always establish eye contact with drivers before assuming that a green light means it is safe for you to cross. This is especially true for elderly folk like me. But it seems youth in particular are often impatient at crossing lights and this video presents one way to keep them from jumping the light. It is very clever and I hope the strategy will be widely adopted. Even then, however, I still recommend eye contact with the nearest driver before stepping onto the road. The video is here: https://www.youtube.com/watch?v=SB_0vRnkeOk&feature=share

Let me know what you think. Just copy and paste the link into your browser. Thanks Ted.
