As much as I disagree with his entire premise, he does give the number per million hours travelled right after that statistic.

Cyclist - 0.41 Pedestrian - 0.80 Motor vehicle occupant - 0.46 Motorcyclist - 7.66

This does not mean I agree with his argument at all, and in fact it is pretty flawed logic to not do something that gives you 85-88% less chance of serious brain injury just because other activities may be more dangerous.

Does this mean you will now wear a helmet while driving, because it gives you 85-88% less chance of serious brain injury?

I am thinking about it, actually. My wife's mother died from a head injury in a car (in the 90s with no air bags). I hadn't thought about wearing a helmet in a car much until reading this, but my car is also equipped with air bags both in front of and beside me. Most of the statistics in this article were before side curtain airbags were as common, and the pie chart is from the 70s when air bags were not very common at all. So I have basically purchased a vehicle that has a lot of the helmet functionality built in. I would guess wearing a helmet with full air bags is probably more dangerous than not wearing one.
