After 6 months of autopilot requiring me to disengage it on the same stretch of road everyday on my commute to work, it has suddenly started navigating the road without need for me to take over. Problem is I don't know if it was the update or the repaving of the road. Construction started on the road a few weeks ago, and due to all of the road work, I drove another route to work for a few weeks. Construction was completed on the road at the same time my HW1 model s received an update. Now I started to take that road again and my vehicle has navigated the road perfectly for three days in a row (every time i've driven it so far!) If some resurfacing and line painting is all it takes, perhaps HW1 will improve with better infrastructure long after updates to the hardware stop, or is the update to the road merely a coincidence and the update actually improved HW1. Darn you no release notes!!! Anyone have a similar experience?
