There's just so many unanswered questions with automated driving that a lot of people don't really want to solve, they just want the technology out there and we'll worry about the edge cases later...as in, we'll worry about it when people start dying. "Move fast and break things", that retarded shit. I hate it. This SV frat programmer mentality is now bleeding over into automobiles, an industry that does indeed need to be shaken up, but not when it's at the expense of lives.
Treating driving software like it's a fucking web application that can be fixed later is malicious negligence.
So your comparison doesn't make sense.
(Have some history in elevation control, because we made some standards in the industry.)
That has no bearing on how common these types of collisions are. The original issue is whether Teslas are more likely to crash into a parked emergency vehicle than a human.
The training has a better explanation: while "number of collisions per mile driven" is vanishingly small, "percentage of law-enforcement deaths as a result of collisions" is very high. Out of the ~1,200 LEOs killed between 2000 and 2008, about half were due to collisions[1].
That alone tells you how such collisions can be rare, but still a top-of-mind issue for law enforcement.
