I agree that 10 g's is a small shock. But think about it this way.
160 lb man drops 16 feet onto his neck. He hits at about 32 feet per
second or about 20 mph. If he decelerates at 10 g's, the force is 1600
lb force. The energy is 2560 ft lbs.

You want me to believe that a helmet will protect me at higher speeds.
Now if I had to be involved in an accident at a higher speed, I would
want a helmet. I am just not sure it would be enough to be of any real
help if I went over the handlebars and hit something halfway hard head
first.

You're right, if you ride head-on into a bridge abutment at 60 mph, you're
probably dead.

Fortunately, that isn't the way most accidents happen. Unless you like
playing Russian Roulette or betting against yourself with 100:1 odds, there
is no credible argument against wearing a helmet.
