Okay, drove an AP car for the first time the other day... The advisor who accompanied me on the test drive told me he had specifically chosen that car because they've driven it enough that it was able to "learn" what to do in most situations. Does anyone have firsthand experience with the Model S' AP learning curve - e.g. was it horrible at first and is it better now? He even went as far as to tell me the new cars they get are HORRIBLE when it comes to AP and they tell you to take over all the time until they learn how to behave. Next up, weather! How does your AP do in all sorts of weather conditions?!
