That's the problem. They're strongly biased towards the do no harm side of the balance - even when inaction causes much greater harm. It's simply a blind spot for them.

They're the wrong group to make the call here, and the politicians should overrule them.

Doctors are supposed to do no harm.

And erroring on the side of caution is what tends to happen in democracies. An authoritarian government is much more suited to taking bold and controversial action. I’ll personally stick with the overly cautious government.

Politicians don't make that determination right now. Self driving cars are a pretty good example. There's evidence right now showing that most systems are safer than human drivers. Yet still they are not permitted for use despite the fact that it will almost certainly result in fewer deaths.
