That is true for FSD in general, but Tesla advertise it as "being around the corner"

Part of the problem with FSD is that it is difficult to make and test incremental improvements on a larger scale. At some point you need to send a big fleet of cars and let an "average" driver drive it without any special safety measures

Another part of the problem is public perception of safety, people are willing to accept fatalities due to human mistakes but even minor accidents caused by FSD are highly publicized

The social acceptance of many autonomous applications hinge on accepting that someone was hurt or killed in a way that was trivial to prevent for a human in control.

The other side of this is that a machine may prevent other accidents that a human cannot prevent. As long as our machines aren't truly superhuman we will have to find an optimal middle-ground (between human and machine control).
