That's a great point. Air travel has gotten measurably safer and people survive car accidents at much greater rates.

I guess there's just something more "understandable" about a plane crashing due to an engine failure rather than software fighting the pilot. Or it's more understandable when someone died in a car crash because they couldn't control a skid rather than Autopilot driving into a concrete barrier it avoided previously because something inscrutable in the programming changed.

Perhaps we're heading towards a world with on average better, but less well-understood, outcomes.
