Tesla to roll out hands-free steering on Model S in 3 months

Tesla Motors Inc plans to offer hands-free steering on its Model S sedan in about three months, Chief Executive Officer Elon Musk said Thursday. The automatic steering feature, which will be available only when driving on the highway, will be part of a continuing series of free software upgrades delivered wirelessly to Model S owners, Musk said. Tesla is among several automakers, including BMW and Daimler AG's Mercedes-Benz, offering over-the-air updates.
