aero dynamics way more optimal nowadays + obsessive optimization of fuel costs etc. + airbags & shock absorbers change a lot. Current design is breakable on purpose to absorb the shock in the structure rather than into human. Maybe not compatible w bumbers

Safety Crash design realized you want a car crumple upon impact, not stay intact. (Which then became legislated) Also design of hood and numbers are now regulated to protect pedestrians in crashes

Asking this very question this morning when I bumped the tire on my son's car and did about $1500 damage to my "bumper". (If only I didn't have 40 years of using mirrors instead of cameras...sigh...)
