Yes, seriously dead. Sitting by the side of a road when a storm blows through the Colorado mountains because of a mechanical issue that you can't fix puts you at risk. Hypothermia is a serious issue in an area where temperatures can drop up to 50 F in a matter of a few minutes. Lightening strikes aren't uncommon in my state and the storms move very quickly. If you are waiting for you buddies to climb a pass so that they can go get the car to come rescue you, you could be waiting a very long time indeed.
