s/w 17.28.4 cf44833 One of your biggest fans here Tesla, but bloody annoyed at this morning's incident, and must say this simply is not good enough. I don't need my car testing my reaction speed in this manner during my morning commute. Car was quite stable on AP on a well marked road as used daily in the lane next to the median, light traffic, clear dry weather, no sun glare. A gentle curve to the left and without any warning the car snatches to the right and comes within a gnats of hitting the metal barrier. How many times does this have to be said - if the AP loses it's way - beep and disable it, don't just head off in random directions applying an amount of steering lock that quite simply no driver would ever use at these speeds. I held off buying an AP2 car due to the early issues and believed they were largely resolved now. Sadly I have to say I am wrong, when it's good it is very good but there are still too many occasions when it will behave completely unpredictably and this ruins its utility. I have utmost faith in Tesla to get on top of this, but for now this has to be another warning to all to take care and really do keep your hands firmly on the wheel at all times (as indeed required by Tesla) as you cannot predict when AP2 will lose the plot.
