Tesla to offer hands-free steering on Model S in three months

Tesla Motors Inc will soon offer upgrades including hands-free steering on its Model S sedan, Chief Executive Officer Elon Musk said on Thursday, but the news did not help the electric carmaker's volatile shares which fell more than 2 percent. It will be available only when driving on freeways or major roads, as part of a continuing series of free software upgrades delivered wirelessly to Model S owners, Musk said.
