Honestly, I've been in two crashes which resulted in hospital visits via ambulance. I don't know if the hospital called anyone either time. (I went to the same one both times) I know I made calls on the first one, but my friends went looking for me the second time since I didn't show for the ride. My phone was in the bike and as we all know, no one knows numbers anymore. I suppose if it was a DOA, things would have been different. They'd find out who to call, between phones and ID's. I wouldn't worry too much about extra stuff....my opinion.
