Again, leaping to erroneous conclusions seems to be your strong suit. Shame you never mastered reading comprehension. If you read REALLY slowly, I'll try to explain it to you at a level you might be able to grasp:

A helmet MIGHT save one's life if they get hit by a car, assuming the non-head trauma injuries are themselves survivable. If you don't grasp the difference between it MIGHT save one's life, and it IS going to save one's life, you really shouldn't waste your time on internet forums, as it's bound to be both a frustrating and humiliating experience for you - even if you fail to recognize it yourself.

That being said, auto accidents are by no means the sole, or even main type of accidents for which cyclists may benefit from having a helmet on. Simply having one's head hit asphalt or concrete from a height of six feet or so, even at low speed, would be such an example.

But again, that would hold more true for someone having a brain worthy of protection, than it would for you, since you are incapable of having such an accident, since it would require you being useless, and you've already explained that only others are so useless.
