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
