Also: Kinetic energy is not measured in foot/lbs.
God spare me from the internet experts.
You forgot to provide a cite supporting your opinion about what is a "more likely scenario". You forgot to cite evidence that bicycle helmets are designed for impacts against angular objects such as curbs. You forgot to cite evidence that, regardless of design, helmets actually
do protect against such impacts. And, "also", you forgot to provide evidence that foot pounds is not a commonly accepted and practiced method of expressing kinetic energy.
Aside from that, great post!
