You know that this was not a bailout, it was a loan, which was paid back 9 years early and with interest. I do not believe this load was the only way for Tesla to survive (I'm sure Elon Musk would have found other ways). It is out of question, though, that this loan was a big help for Tesla
If Tesla is around in 30 years. Remember that Tesla was going to go bankrupt 9 years ago before government bailout. And warranties can become worthless when companies go bankrupt.
