In its Autopilot report today, the NHTSA reported that accidents in AP-equipped Tesla's dropped by a remarkable 40% compared to Tesla's without AP. According to the NHTSA data, AP-equipped Teslas appear to be almost twice as safe as Teslas w/o AP. And this likely understates the safety benefits of AP, since AP is only in use part of the time. NHTSA’s full final investigation into Tesla’s Autopilot shows 40% crash rate reduction The key figure is below. Congrats to Tesla and the Autopilot team -- pretty amazing result for Autopilot's first year.
