Transcript for Gas Prices Plunge Below $2 per Gallon
Also on the economy tonight, the good news about gas prices. The national average now $2.10, and just look at the map this evening. 45 states now with at least one station, gas under $2 and in one town in Texas, $1.47 a gallon. I should have gone while I was in Texas last night. Let's get right to ABC's Clayton Sandell, who is there tonight. Reporter: That huge sign heralded $1.47 gas is drawing a huge empty tank crowd to Texas, for one of the lowest, if not the lowest prices anywhere. Good news for Perry carbo. His limo company uses two stretch hummers. You get seven miles to the gallon. Filling one hummer used to cost 100 bucks. Now, he can fill both for that. What is it like to look at a number that low? Ah -- good for the bank account, that's for sure. Reporter: Good -- a for a lot of bank accounts. $750 less this year compared to last. But at the Detroit auto show, more fuel efficient cars are now taking a backseat to gas guzzlers. Ford's CEO tells ABC's Rebecca Jarvis, the ups and downs are a key challenge for automakers. Consumers are really smart. They know gas prices are down, but they may go up and they want to make sure whatever vehicle they have, even if it is a little bigger than what they thought they were going to buy, they want great fuel economy. Reporter: Lower prices can bring a drop in production, meaning potential layoffs for thousands of oil and gas workers. And of course, that affects people spending money which affects our business that way, too. Reporter: Of course, the question tonight is, when prices like these will finally bottom out, and the fact is, we don't know. But it is now looking more likely that by the end of the month, the entire country could see an average price below $2 a gallon.
