Elon Musk tweeted this morning saying that he is “hoping to start the rollout of 8.0 on Wednesday if no last minute issues discovered.”

The biggest change in Autopilot is an increased reliance radar. “After careful consideration, we now believe [radar] can be used as a primary control sensor without requiring the camera to confirm visual image recognition,” wrote Musk in a blog post on Sunday. The sensor was first installed to Tesla vehicles in 2014 and this update may be because of the fatal car crash of a Tesla Model S in which the driver was killed while using the Autopilot service in May.

Also included in the update will be a “geocoded whitelist” of objects such as signs and other obstacles that result in the misidentification of objects and the vehicle making unnecessary braking or dangerous maneuvering. The fatal accident in May was caused when Autopilot did not recognize a truck that was turning towards the car and instead identified it as an overhead sign.

To those with Autopilot always drive safely. The update will be delivered over the air to eligible vehicles.
