I'm no expert on any of the selfdriving features (I still self-drive my 1984 Volkswagen with tlc) but from what I hear and see, Tesla is amongst the worst when it comes to selfdriving and e.g. Volvo or Volkwagen is way ahead.

Their marketing, however, is top notch, so whenever Tesla fails to deliver, people conclude that 'all selfdriving must be crap'.

Is there something called 'Law of inhibiting leadership'? In which an underperforming leader of a segment holds back the entire segment?
