I'm not a regular Autopilot user but at the weekend did some long motorway runs. As per reports from others it was a much smoother experience than on any previous occasions I have used it. In addition to maintaining the lane positioning there were no panics when passing large HGVs and no instances of unexpected sudden slowing or braking. Some of the miles were as darkness fell and there were no issues adapting to the changing light levels. Earlier in the day I had caused a car panic when I saw that the lights were on in circumstances where I felt they were unnecessary ... I was on Autopilot but "in a moment of madness" decided to switch them to off ... instead of simply putting up a message saying I'm not allowed to do that anymore it did switch off the lights but then immediately gave me the nuclear warning klaxons and flashing screen saying Autopilot unavailable TAKE CONTROL! A more graceful management of that situation should be easy to achieve!
