Hard to say. Many of the Closed Head Injuries occur among the elderly and that cohort is included in the pedestrian data, so it is somewhat skewed given the enormous number of elderly who experience falls. TBI/CHI are largely dependent on the head velocity at the moment of impact. In a car traveling 60mph, obviously the impact forces can be extremely high, versus the velocity of a falling body as a pedestrian falls and hit their head. That's the whole reason for protecting the inside of autos with airbags (Head, front, side). So, they tend to reduce the need for helmets in automobiles. The same rationale for opposing those airbags existed at the time laws were changed to mandate airbags = will increase the cost of the automobile, is intrusive and big brotherish, etc. etc. Luckily as a society we came to our senses and mandated seatbelts, head, front, side airbags despite all of the economic arguments against the law and rules. There are times when even cycling advocates should consider the greater social good in terms of reducing head trauma and death by requiring helmets particularly for children.

I feel like I read an analysis somewhere that use of helmets by pedestrians and MV occupants would have as great/greater an impact on preventing TBI as/than it does for cyclists.

Maybe I made it up or maybe the analysis was flawed, but it seems like a viable question. If helmets could help prevent some injury to pedestrians, should they be mandatory? Why aren't people in motor vehicles required to wear them (like race car drivers).

    > Barriers to helmet use include cost, the wearability of bicycle
    helmets, and a lack of knowledge regarding helmet effectiveness
    (33). In addition, some school-age children (i.e., children less
    than 15 years of age) believe that wearing a helmet will result in
    derision by their peers (34). Among older children and adults,
    rates for helmet use are influenced by some of the same
    demographic factors as rates for seat belt use (e.g., age,
    education, income, and marital status) (14,33), and some of the
    reasons given for not wearing helmets are similar to those given
    for not wearing seat belts (e.g., rider was on a short trip,
    helmets are uncomfortable, and negligence) (14). Approaches to
    overcoming some of these barriers to helmet use include
    community-based programs (33) and bicycle helmet legislation,
    which may be particularly effective among school-age children
    (34-37). http://www.cdc.gov/mmwr/preview/mmwrhtml/00036941.htm
