I thought he was implying that you should judge crashes per incident, a proxy of which is bicycle crashes per capita. If you have 5 more deaths a year but 5,000 more people riding regularly, then, yes, in absolute terms, more bicyclists died. But as a percentage of the moments spent riding by all citizens, crashes resulting in death became less frequent. Because you increased the denominator.Now if instead you don't like analyzing by percent of incidents and you favor overall numbers, then you should recommend helmets for all human beings, especially drivers, and definitely all pedestrians. (most of the statistics I am looking at are on the CDC website). So 2% of people who died as a result of a motor vehicle crash were bicyclists. Let's call it 37,000 road crash deaths and 740 of those were bicyclists. Broad averages, not any specific year. But it also says that traumatic brain injury deaths in 2013 were 19% of motor vehicle crash deaths. So 7,030 people died from head injuries related to motor vehicle road crashes. If only 740 of those were bicyclists, that means 6,290 weren't. Assume some of those were pedestrians, and you still have thousands of deaths that may have been mitigated by everyone in a motor vehicle wearing a helmet. Pedestrians would doubly benefit, because the leading cause of death by traumatic death by brain injury is a fall, usually of a pedestrian. So helmets for everyone always! We need to save lives, right? |
