I find this argument entirely uncompelling. There are an inordinate amount of risks imposed upon me while operating in society which I neither agreed to nor would I given the choice, aside from in a hand-wavy “social contract” sense.
However as a member of society I am in fact compelled to accept myriad risks on a daily basis imposed on me for the benefit of others, or the benefit of potential scientific advancement.
This concept that a society cannot morally make risk-reward decisions in the course of technological advancement is entire bunk IMO. Government can absolutely morally make these trade offs and does so constantly.
I feel pretty good about the current legal and regulatory frameworks and the technical chops of the NTSB to monitor developments in self-driving R&D adequately.
One thing I am certain of is that we absolutely must succeed in developing, productizing, deploying, and ultimately mandating self-driving technology. Millions of lives and trillions of dollars are at stake, and yes, society as a whole will incur individual loss of life in the pursuit of this goal. An attempt to develop the technology with zero risk of collateral damage would in fact cost many more lives overall.
