We are in that same position now as I was buying my 2019 Model 3 from the Tesla website last year. Knowing that as stated by Elon that the car would self drive by the end of 2019. How confident does everyone feel? You see if I look overall at what my car could do then in terms of AP FSD and now it displays road cones, dust bins and traffic lights. It still phantom breaks, tries to sometimes steer off the road in AP for no good reason, doesn't recognise speed limit signs and at motorway speeds suddenly slows when it loses the speed limit. All of these are smoother with basic lane keeping assist and traffic aware cruise control methods in other cars currently. (Also experienced in an eniro it has smoother AP currently) It also parks worse than a 2017 ford focus. All of these things are from actual experience and are the reality of my ownership. But will my full self driving computer model 3 be able to drive across London on its own this year? I place the marker now in the sand and await the fiction to turn to real fact. Because I am on the edge of bailing out here if I am honest because reality with AP for me is that it has not improved much in almost a calendar year making the same mistakes.
