Do you ever drive a car? Do you think the risk is "acceptable"?

And don't get hung up on semantics, "acceptable" doesn't mean it's not terrible, it means that it's not feasible to prevent every risk with that danger:cost ratio. Especially because anything that causes a drastic reduction in flight will increase car trips and probably cause more deaths.

This is of course different from someone lying about the level of risk. But some risks really are "acceptable".
