I'd say it's also because today we instinctively know FSD cars have not proved their skills in the same conditions a human driver does every day. Racking up millions of miles by following a line or the car in front on the highway is far from dealing with a crowded city center, bad weather, unexpected issues that have no clear rules of engagement, etc.

Tomorrow the situation will be different. But it's hard to trust such a broad safety claim knowing it's based on partial data and say "the failure rate [for self driving] is on average /better/". Comparing failure rates obtained is such different conditions is misleading.

Self driving cars are like a student driver with supervision. They currently drive in relatively controlled environments, or at least ones with very forgiving conditions, and are learning. And just like student drivers with supervision they are relatively safe. Until the moment they're exposed to the full set of driving conditions without supervision. We intimately and instinctively know and trust how the learning process work in humans. For cars not so much. Not yet anyway.

> We seem to accept being killed by someone else, since that is how most of the 40,000 people are killed every single year in the US. I don't hear too many drivers complaining about that.

As a driver, that's not really something you have control over, apart from driving defensively. Your AutoPilot Tesla can still get T-boned in an intersection by some guy running a red.
