Science on a motorcycle

Accidentology is a little known science which identifies the most frequent causes of transport accidents to develop appropriate solutions, whether these involve raising drivers' awareness of the dangers of the road or improving roadway layouts.
The example shown is the practice of motorized two-wheelers moving up traffic lines, which is particularly common in large city centres. Dangerous for motorcyclists, who are more vulnerable on the road than motorists, this practice is also dangerous for pedestrians crossing between vehicles at a red light or in a traffic jam.
