На самом деле, картинка, как обычно случае инфографики, даёт переупрощённое представление. Если посмотрите оригинальные статьи, то там, к примеру, такая цитата: "The absolute numbers of lane splitting crashes are small and therefore need confirmation".
Статья с метаанализом пишет:
lane splitting motorcyclists are:
● More likely to be weekday commuters
● More likely to be obeying the speed limit
● More likely to wear a full face helmet as opposed to an open faced or novelty helmet
● 65% less likely to be under the influence of alcohol
● More likely to be properly licensed
● Less likely to be carrying a passenger
Возникает ощущение, что это "I can drive safely, so I will lanesplit", а не "lanesplitting is safer, so I will do it".
