The Model X that Customers receive during 2015 will be vastly better than anything Tesla Motors could have provided in 2013. Critics and Naysayers love to point out missed dates for Tesla Motors. But in the midst of their angst for Elon Musk, they never bother pointing out the reasons for delays.
When someone else brings up those points, and that they make sense/were neccesary/repesented a good tactical choice, Critics and Naysayers predictably play the Tesla Kool-Aid/Musk Fanboi Card. They claim that there is 'no excuse'. They say that a 'more mature' company leadership (someone with their own resume, for instance) would do a much better job of keeping things in line. Me? I call [BOLSHEVIK] on that line of... 'reasoning'.
There is a difference between an excuse and an explanation. Critics and Naysayers demand explanations, then claim they are no excuse -- when they were given an explanation, and didn't ask for an excuse. Either you trust the leadership at Tesla Motors, or you don't.
If you don't trust them, why bother wasting your time or money bellyaching about their efforts? Volkswagen Group will gladly sell you a nice gasoline hybrid or diesel powered Cayenne, Q7, or Tourareg instead of a Model X. Enjoy!
