You are thinking as we thought: If we lost a phone or crashed, we'd want others to step up and return the phone/help us out.
In previous crashes people have stopped and offered help. And we feel compelled to do likewise (cgallagh is trained as a first responder to refinery emergencies, and I have ACLS training), so stopping and helping is a no-brainer for us.
I'm thankful that so far we haven't encountered really ugly stuff. Even so, if we're first on scene, we'll do what we can.
