>If you were given the choice of two different dangerous roads where one road had a 30% lower chance of getting into a life-threatening car crash, you would probably think that the choice was obvious, not that the two roads were basically the same.
You could absolutely think that they were basically the same, depending on the base rate. The differece between a one-in-a-million and 0.7-in-a-million is 30%, but it wouldn't be humanly perceivable. We're all likely faced with situations like that regularly. Differing airlines probably have much greater variances in their crash statistics, but it just doesn't matter in 99.99999% of flights.
