The Blue Oval company tripled the number of electric vehicles sold last month, led by robust demand for the F-150 Lightning truck. Ford’s share of the overall EV market is also up 3.1 percentage points over last year with 7.0 percent share — which still places it as a distant second to Tesla. BlueCruise, the company’s hands-free driver assist system for highways, is being used by 83,000 customers, who have used it for over 21 million miles.
