I have already said I am not against their development per se.
People are saying "a small number of people might die and no one wants that, but it's impractical-to-impossible to guarantee that zero people will die." And you are asking, "but why? But why?"
Now and then there at washing machine deaths. Society accepts these because they're so rare and because it would be impractical to completely prevent them.
Compared to the number of road deaths most experts believe will be prevented over time, the few deaths we may encounter from training deaths seems completely inconsequential.
Are you sure about that? Society just accepts them and moves on?
There aren't lawsuits? There aren't recalls? There aren't redesigns? There aren't safety measures taken so deaths don't happen again? There aren't investigations? Fines aren't levied if they violated regulations? Regulations aren't passed in response? Everyone just rolls over and says, "This is just the price of washing clothes" like we are with autonomous cars?
Accepting that accidents will always happen does not imply you learn nothing and improve nothing.
I agree, beyond a select few individuals who have not posted on HN at all, I do not see or believe that anyone is calling for unnecessary deaths if they can be avoided.
I do believe that we're letting optimism and good intentions get the better of us, by allowing our interests in the betterment of the humanity to align with the interests of business, which would like to see autonomous cars on the road unencumbered, unregulated and unquestioned as soon as humanly possible.
Hence why I am advocating for a level of healthy skepticism. I am imploring posters who are taking it on faith that autonomous vehicles will solve the problem of automotive deaths if we suspend our disbelief, to apply the same level of skepticism to this field as they would, say, biotech.
What's that classic example, robocar has to make a choice between (potentially) killing a bus full of school kids or a bunch of adults standing around on the sidewalk.
