BINGO !!
How did Shep get there to where those people are stranded on the highway? Did he get helicoptered into there? Did he drive there? Is he going to stay there until all those people find out where they should be going, or will he, when his shift is over, bug out to somewhere safe with electricity, a/c, water and food and come back to give more drama when his next TV performance time comes. If he was truly concerned, he'd quit emoting on the boob tube and use the resources he has to begin taking those people to safety. It's all about the ratings.
