Earlier quoted context omitted.
Tesla has been designing and producing road-worthy vehicles for 14 years. If they're in startup-hair-on-fire mode right now, something is very wrong.
Which new automaker of the past 40 years do you compare them to as far as measuring what is wrong?
Seems like blind replication isn't the answer alone ( http://www.tandfonline.com/doi/abs/10.1080/00207540701223493... ), which is unsurprising, but Tesla's sales targets and their current production line process as-reported seem at odds.
This stuff is very well-studied and making basic errors seems like a problem of hubris coming from a software industry that's in a much less mature state.
