I LOVE Tesla autopilot. I use it every chance I get. The over air updates have improved every time. There are minor tweaks and alterations that would be nice, but I am excited for higher integrations od autonomy, and I trust the present version for safety and reliability with 95% confidence (at 100%, I could sleep while it drives).
Very few. City: Minor issues while crossing through intersections and staying a little too close to curbs or one line than I would prefer Freeway: Going over the crest of steep hills, the vehicle sometimes lose sight of the lines. When it does, it tends to veer left or right, rather than stay on a straight path. It also will not steer away from items or small obstacles in the road, as far as I can tell.
