I agree that there are aspects of the Tesla safety record which have caveats, but even when I take those caveats into account, I still come out thinking of the Tesla as being relatively safe. The same feature which adds danger at every update is one that also has the potential to add safety at every update. Eventually for example, that same update feature is expected to bring the car to the point of being superhuman in its ability to drive safely. The inability to rely on the autopilot means that I'm still responsible for my own safety, so the autopilot safety isn't as important as the car's safety in general.
I disagree that their communication is only reflective of them covering their ass. I feel their is the expectation that self-driving is going to prevent more deaths than it causes. Especially as the technology improves, but even to an extent now if only through the virtue of it not being a system people should be using without being ready to intervene.
Don't get me wrong here, you raise good points. I just don't think it's a case of blatant evil.
Also, if you have the link to the math, I'd love to read it.
