I wonder if there's even any citations that can directly show that a 2024 car is "much" safer than a 2004 car. Without relying on NHTSA's safety rating system, which is an indirect proxy at most (and probably has changed multiple times for "reasons"). And without being confounded by changes in regulatory measures.
I'm struggling to find the original document/page I read on this, but largely, "a car having better parts is due to the road having features that benefit these parts due to generations of studying the way cars behave in that set of circumstances.
Autos are designed around and for the roads they will serve, not vice versa. This is the bane of auto manufacturers who want to make one tail light housing for all their cars in all their markets.
it's a bit more easy to read data comparing for example safety in Euro market vs American market (there are fundamental differences in safety thoery; lighting, ride heighgt, weight, engine size etc. As opposed to looking at changing trends in one market over 20 years, which are largely stylistic.)
I think it depends on what you're trying to gauge for safety.
Pre-2000 satedy improvements were heavily about WHEN you get into an accident...
Post 2000 it is heavily is heavily DON'T get into an accident, and it's heavily electronic. Anti-lock breaks, lane change vehicle detectors, unintentional lane change warnings, auto-breaking before collisions.
I certainly agree with the general vibe that cars do too much now, but I'd rather have a dumbified 2010+ish car
