I may look into a plastic card on a necklace with identity and health info - doesn't sound comfortable though.
Unfortunately, no system is fail safe. Some are better than others. Having worked on both sides (cyclist and first responder) I can say that anything you do that will provide them with the needed information, in the event that you are not able to, is good. However, for first responders to have that info, they need to know where it's at or it stays at the scene. The more visible this info is, the better. And it's true that the phone can break but something like a RoadID with ICE numbers on it is still better than nothing.
Since we're talking trauma here, paramedics aren't going to administer much in the way of medications while enroute since there's really not a lot of medication they can give, especially if you're unresponsive.. I'm more concerned with the hospital treatment. Since they have the staff to do so, the phone numbers will get called, provided they have them.
