Driving has gotten much safer (measured in injuries/fatalities per million miles) over the past century. Obviously the safety features help much more than they

  Sure. Crumple zones and seat belts have both made a huge difference, particularly in the last 20 years or so since much more stringent crash testing. Having picked off low hanging fruit, it's naive to assume every feature comes without negative consequence. Some of these have demonstrably moved the fatalities elsewhere, so whilst fatalities for occupants have been reduced, pedestrian fatalities are rising - as a direct consequence of increasing car safety. Some, like lane assist, may eventually turn out to even be counter productive to overall figures. I'm not sure if there's been much research on the real world consequence of many of the newer ideas yet.
