In recent years, e-scooters have proliferated in cities worldwide, offering citizens a novel and convenient way to get around, but their arrival has not been frictionless. Commonly voiced concerns are that e-scooter riders break traffic rules, ride too fast, and park inappropriately. Perhaps most concerning is that crash databases, as well as insurance claims, show a clear and disproportionate rise in crashes as the number of e-scooters increases. Local authorities have sought to address these concerns through measures such as speed restrictions, requiring users to wear helmets, designated parking areas, and limiting the number of scooters or operators allowed in the city -- or even outright bans.

"E-Scooters are not necessarily more dangerous than bicycles, but they are often perceived as such, possibly because of their unfamiliarity and the behavior of their riders," explains Marco Dozza, Professor in Active Safety and Road-User Behaviour at Chalmers University of Technology, and lead author of the new study.
