Tesla seems to take its responsibility the way I wish all companies would when it comes to their products. It inspires trust. For me, anyway, and I think many people feel the same way -- many people in this thread, anyway :) Also, Tesla has a pretty solid reputation when it comes to supporting their own products, so that probably helps.
The alternative is to say "Okay Tesla made a mistake, they suck for making a mistake and I don't trust them anymore" and that's usually unfair because everybody makes mistakes.
There is value in blameless post mortems, in openness and how you handle a crisis.
It is not the most important thing though. The most important thing is how you set up and fix quality so people don't die.
This reminds me of the Zen teaching where one points with his hand to the moon. And people forget about the moon and focus on the hand pointing instead.
