Nice job!


Impressive, but also slightly misleading. The mangled plastic or
vinyl "bumper cover" is mostly cosmetic, not structural. Behind it is
a rectangular cross section pipe that serves as the real bumper. Any
impact is absorbed by either shock absorbers, or blocks of foam. The
other function of the bumper cover is to ride up and over anything it
hits. Hitting a high curb or another car transfers less energy if the
car rides up and over whatever was hit. That's my guess(tm) what
happened here. The bumper cover was in the process of riding up and
over the bicycle rear wheel. Apparently, there was enough crush depth
in the bumper cover to not lift the front to the car off the ground.
Had that happened, methinks the rear bicycle wheel would have potato
chipped or been squashed.
