As a whole this is true and could probably be bested. But it would have to be by many magnitudes of order to have people accept it. There's a feeling that isn't necessarily true that one can control their destiny driving and avoid being a statistic.

But if autonomous cars were even 90% less fatalities it would still be hard to get humans to give up control for that. It would have to be on the realm of air travel safety.
