Meanwhile, consumer unease could spur a sudden increase in gas prices. “If motorists suddenly panic, out of fear that gas won't be available or will be available at some stratospheric price, they 're going to line up at gas pumps and create a gasoline shortage, ” says Geoff Sundstrum of the American Automobile Associatio&15.
