How does the first fatality in a Tesla on “autopilot” affect insurance? At this point, not at all. The insurance companies that Chartwell Insurance Services places coverage for their insureds with are not expected to reduce their policy language. Will some insurers implement exclusions for cars on autopilot? Maybe in the future. The most important lesson from this terrible tragedy is that autopilot is not a substitute for driving. Keep your eyes on the road and save movie watching for movie theatres, airplanes and your couch. If you want to better understand what happened see this diagram from the New York Times.
