THAT’S A PRETTY BIG SOFTWARE UPDATE: Tesla Model S: Summer Software Update Will Enable Autonomous Driving. “Let’s be very clear about one thing, though: no matter how fancy your Tesla’s autopilot is, you are still legally required to be in control of the vehicle. This means that if you decide to use the autonomous highway driving capability, you’d better be sitting there paying just as much attention to the road as you would be otherwise, because if anything goes wrong (like, if the autopilot gets confused), a resulting accident is your fault. Just the same as if you’d lost control of the vehicle yourself.”
