Setting aside the frequentist probability premises, the argument that "Cars are way, way, way more dangerous than airplanes" -- while true, and reasonable, and would not be as dismissive a point if it were recognized that car culture is so normalized and widely internalized by individuals and less so the fault or ridiculous irrationality of said individuals -- is not really relevant to the argument that "Airbus is a safer airplane than Boeing given how each company is run nowadays."
Like, based on your simple frequentist argument, should Boeing be above FAA scrutiny? Let's just tell the FAA to spend more time on reforming car culture, too? People shouldn't bother voting with their feet?
If you enter a car, your chance of dying on that trip is lower vs. when you enter a plane.
