Tesla CEO Elon Musk is finally sharing the "major improvements" coming to Tesla's Autopilot feature. In a press call this afternoon, Elon Musk described the "massive" 8.0 Autopilot software update, which turns the existing radar system inside Tesla cars into a primary source of information for the vehicle's self-driving features. Musk said that with "fleet learning" the update will offer "probably a three-fold improvement in safety," and called the coming radar-only braking feature "superhuman." The over-the-air software improvements are expected to be "deployed worldwide in one to two weeks" to Tesla Model S and X vehicles produced since October 2014, said Musk in a post on Tesla's blog. Musk teased the 8.0 update on Twitter nearly two weeks ago.
