I could be completely off but I was telling a friend about how I wanted to get a Road ID and he told me that the EMTs will still automatically look in your bag/panier/pockets for a wallet with ID (regardless of wrist identification) so I ended up saying "well I always carry my actual ID so no use spending the extra money on another..."
Again, not saying this is hard fact. Just an opinion I recently heard.
Life goes by pretty fast. If you don't stop and look around once in a while, and do whatever you want all the time, you could miss it.
