I have a weard issue with my Model S 2016 navigation. Car seems to drive 1 or 2 degrees different direction from my route. It typically starts at home and last time on sunday when I was about 50 km away, car seemed to go about 1 km off from road. Then suddenly car founded GPS and jumped to road, but only to start again driving slightly wrong angle... I have taken a couple of videos about issue, but not sent to anyone yet.
