Perhaps you misunderstood my post. I was arguing in favor of bike helmets.
People often argue against the use of bike helmets by pointing out that a helmet won't save a rider who is hit head on by a car traveling 60 miles per hour. My point was that extreme examples can be used to argue against the use of any type of helmet---military, construction, etc. If only extreme circumstances are considered, then all helmets are arguably useless.
By the way, I believe that most modern construction helmets are polyethylene, not steel.
