The main reason I am considering buying a Tesla is so that it can drive me to work while I do something else (work while it drives). I understand we are guessing, but how soon do we think this will be possible? Are we talking 1-2 years? 3-5 years? or should I get real about this and understand that it could be more than 10 years before it happens? (Yes, I've seen the videos of these cars driving themselves, but as I understand it, this isnt available to me.)
