To rephrase the question - are you prepared to slightly increase chances of injury of your family for the next 5-10 years, if leads to drastically increasing their safety after 5-10 years, and forever after?
This is not rephrasing, this is changing the question to something completely different and wrong.
In addition, not providing any data there or alternative is just misleading.
Ex: I would NOT accept increasing the risk by 10 in the next 5 years to reduce it by 30% afterwards. I would NOT accept increasing the risk by 2 during 5 years if we could instead just increase it by 5% during 10 years and get the same result. I would NOT accept even having the same probability if we could first learn more and take 2 more years and a few billions to get a more stable technology before launch.
The point is, the "what if it is your family" appeal goes both ways. The downside of a laissez-faire policy towards self-driving cars could fall on anyone, but so does the upside.
You have to be quite shortsighted to say "no".
