If people demand their cell phones work after an event that will have everyone using their cell phones at once, be prepared for your bill to at least triple in expense. No network can handle a sudden spike of demand and for them to do so would be extremely costly. I remember the days before cell phones and I've seen landlines fail as well during emergencies as capacity increases.
The highway example was perfect and hits home since I live in a hurricane area. On a normal days our highways are acceptable. When an evacuation is ordered, what is typically a 20 minute drive turns into a 4 hour drive (very literal on that).
Do your part. Don't try to call people after an emergency. Figure out an alternative such as Twitter or Facebook for status updates. Get yourself an emergency plan with your family and setup a meeting location in the event of a complete communications failure.
Also the network will prioritize 911 traffic and each switch reserves capacity specifically for 911. That's not to say it won't fail since 911 only has so much capacity going into each of their answering centers.
