I'm not sure I understand
What he seems to be saying is "Show us it's thousands of times safer than a human at the wheel, or we won't allow it on the road". This is akin to saying "We don't need airbags, there have been a billion crashes with them, 1 million lives saved, but one person died from injuries caused by the airbag. Ban them, they are dangerous!"
I still think there's a way to go, but I expect automated cars to be tens of times safer than meatbag controlled ones at first. That should still mean 90% of fatalities gone... Surely that's worth it the occasional screw up!
We shouldn't expect perfection. We should expect them to be safer than the dickheads on the roads right now, but 2 crashes and a single fatality from a badly-named smart cruise control system in a large number of miles driven has everyone in a panic.
