If you need to be reminded with three audible warnings within an hour, the Autopilot system disengages and remains that way until the car is next restarted. Several times, as I drove in the freeway fast lane with Autopilot engaged, the Tesla began to veer toward the center divider. In each case, I steered the car back toward the center of the lane, automatically disengaging Autopilot. And with the new version of Autopilot, Tesla has integrated that message more fully into the system. And maybe, as Tesla contends, Autopilot can help a responsible driver avoid accidents.
