U.S. Transportation Secretary Anthony Foxx said there was no need for owners of recalled General Motors Co. cars to stop driving them. In a letter to senators, he said that government engineers have found that if owners follow GM's advice, there's little safety risk to driving the cars. GM is recalling 2.6 million cars worldwide to replace ignition switches that can suddenly slip out of the run position and shut off the engine. That can knock out power-assisted steering and cause crashes. GM says at least 13 people have died in crashes from the problem. GM is urging owners to remove everything other than automotive keys from their key chains, which Foxx says should sufficiently mitigate the risk until the switches are replaced. - AP
