U.S. auto sales are about to surpass a dubious milestone.
If this year's blistering sales pace holds up, more than 17 million new cars and light trucks will be sold.
That would not only be an astonishing comeback from the low of around 10 million sold in 2009, when the Great Recession sent Chrysler and General Motors into a bankruptcy which Ford Motors escaped only by massive borrowing.
It would also be a feat rarely achieved in the history of America's car industry.
