As Mikael Colville-Andersen and Hart Noecker of Rebel Metropolis have pointed out, one is much more likely to have a head injury in a car than on a bike. The absolute number of head injuries is staggering in comparison; Stromberg shows that even looking at the number of injuries per hour of travel, which compensates for the fact that there are a lot more drivers than cyclists, the rate of head injuries is not significantly different between walking, cycling or driving.
In fact, if anyone needs a helmet, it is the pedestrian, who has even higher rates of head injuries than cyclists.
