But fewer than 500 are bicyclists.

And "Causes of Traumatic Brain Injury :    Motor Vehicle Crashes
account for 50% of all TBIs. This includes autos, trucks,
motorcycles, bicycles, and pedestrians hit by vehicles.
     The leading causes of TBI vary by age: falls are the leading
cause of TBI among persons aged 65 years and older; transportation
is the leading cause of TBI among persons under the age of 65 years.
     Estimates suggest that sports related brain injury accounts
for close to 300,000 injuries each year, with winter sports such as
skiing and ice-skating accounting for close to 20,000 brain
injuries. (7) "

Again, bicycling is barely mentioned, and is justifiably given no
more prominence than autos, inside which far more incidents of TBI
occur.

I don't really fault you for having believed that bicycling is an
unusual and  horrible risk for TBI. After all, the propaganda
machine has been in high gear for decades. But it's now time for
you to educate yourself and put things in the proper perspective.

But I _do_ fault you for repeatedly mischaracterizing my position.
At no time did I state our otherwise imply that "bicycling is an
  unusual and  horrible risk for TBI. I stated this unequivocally
several times already.
But now it's time for you to stop building strawmen and try arguing
objectively rather than emotionally.

Zen, you have not precisely said "Bicycling is such an unusual risk
for TBI that you should always wear a helmet when you ride."

But you _did_ confess that you regularly tell people that if they are
going to ride on roads - normal roads! - they should always wear a
helmet.

Why do you always seem surprised about normal roads?

As far as we know, you have not said the same to pedestrians or
motorists, to skateboarders or scooter riders or joggers. That alone
is strong indication that you're treating bicycling as unusual.

I tell my grandchildren they can't roller skate, skateboard, or ride
their scooters without a helmet while under my care.

 
Really!
 
Do you let them run without a helmet? Say, playing tag?

yup
