My Tesla has full self driving supervised. When I use this feature, since about three updates ago, my Car has started braking for no reason. It hasnt happened on a freeway, but, but on secondary roads, it will brake and try to come to a stop. It seems to do this, when there is a shadow across the road, or when there is a puddle in or near the road. Sometimes it will brake for no reason at all. I I have come close to being hit from behind. I think this is a dangerous situation that needs to be looked into.
