ROAD iD is one of the best ideas I've ever seen. As a paramedic, I recently treated a patient who was wearing a ROAD iD. I could not believe how easy it was to get their medical information from their Interactive ID. I just read the serial and pin to our dispatcher, and she was able to get the patient's medical info and radio it back to me...all while on the scene of the accident. After that, I knew I had to get a ROAD iD for myself. I can honestly say that I believe that everyone who is active should wear one of these -- the more people that do, the better!
