If you include the riders who die then then it drives down the average to $3,000 but with 200 people the net cost is still $600,000. Either way your net cost is still going to be your net cost, it's just the average that drops if you include the riders who were DOA.

Yes, I understand that.
I should have read a little closer. I had assumed that mentioning the differences meant that the earlier studies had had differing results, but they don't explicitly state that.
If the average cost(including DOAs) is greater for helmeted riders than unhelmeted, then requiring helmets is going to raise total costs. Of course, that ignores any value of "Not being dead."
