"Watching the Florida evacuation does make me wonder what I'll do for gas if I find myself running away from a hurricane. Traffic is going to slow down to a crawl, and your car will idle a lot, eating up gas without getting you nearer to the destination. An 8-hour drive might turn into a 16-hour drive, with no way of getting gas. Let's assume that I can find all the gas I want near home. Carrying 10-15 gallons of gas in the trunk seems like a bad idea. What would you do?" -from Bingley

Drive a Prius or similar hybrid. When moving very slowly or stopped, the gas engine is not running - perfect for our crowded California freeways. The pics of I95 look like any rush hour parking lot here in SoCal....
