"Auto sales are growing so fast that Detroit can barely keep up. Three years after the U.S. auto industry nearly collapsed, sales of cars and trucks are surging. Sales could exceed 14 million this year, above last year's 12.8 million. The result: Carmakers are adding shifts and hiring thousands of workers across the country. Carmakers and parts companies added more than 38,000 jobs last year, reaching a total of 717,000. And automakers have announced plans to add another 13,000 this year."
