But Musk's numbers are much lower than everyone else's and he usually some percentage late, Not decades. Sometimes he is even on time.
He does things that many claim are literally impossible, who cares if they come 10% later and that is 3 months. If Telsa hits the production numbers by June they are still doing something that GM and Ford once said was decades in the future.
This is where I am too, I could see him aiming for 500k cars in 2018 and only shipping 425k due to some shortage. I could not see it taking until 2022 for him to get to the 500k mark.
