My time in the Marines has shown the value of identification. We may not be in combat situations, but believe me, anything can happen at any time. I didn't use a ROAD iD in the service, but I used dog tags.
Many of us had our information tattooed on our torsos, just in case we were taken prisoner. That's how important it was to have identification.
I no longer wear the dog tags, but I do feel better when I have my ROAD iD on when I run, bike, swim, or even walk. I even wear it in my normal street clothes a lot of the time. I actually have several of them, and several bands.
By the way, I was also an EMT. Trust me, anything can happen, at any time.
