The data reported that drivers will drive an average of 8cm farther
away from cyclists without helmets
8cm = 3 inches. The size of this effect was smaller than the effect of
positioning on the roadway, type of vehicle, or the gender of the rider.
Still, interesting paper.

Half a standard penis, although the ISO still need to standardise this
unit.
I wonder whether the psychological, perceptual effects on the cyclist
(not the drivers) were completely controlled for.
I could imagine that the rider would ride somewhat differently, perhaps
unknowingly, with and without a helmet. Especially if he were
conducting a study and had a point to prove.
