The head on shows it well. The smart car not only stops faster it
actually recoils back.
While its cage might be intact, if a human were inside your guts
would be a mess from the deceleration more so than the larger
vehicle. It isn't fenders crumpling that causes death, it is the
force of impact on the human body.
It's conservation of momentum. If a 5,000 lb vehicle collides
head-on with a 2,500 lb vehicle, both traveling at 60 mph, the
larger vehicle is suddenly slowed to 40 mph and the smaller
vehicle is suddenly traveling backwards at 20 mph.
Immediately after the collision the occupants of the larger vehicle
are flying toward their dashboard at a relative speed of 20 mph,
while the occupants of the smaller vehicle are flying toward their
dashboard at a relative speed of 80 mph.
Both vehicles may have seat belts and air bags, but I think I would
rather be in the heavier one for a better chance of lesser injuries or
of survival. I'll stay with heavy vehicles. I'll keep on paying for
gas guzzler taxes at purchase, for higher gas costs at the pump, and
for alternate fuel subsidies for people who are willing to cram their
families in those little cracker box deathtraps.
