Portland's Bureau of Transit did a 120-day study of scooters here which has some interest bits of information. The PDF is here: https://www.portlandoregon.gov/transportation/article/709719 https://www.portlandoregon.gov/transportation/article/709719 Findings include that injuries did rise, but most didn't warrant a hospital visit. There were no deaths during the study period. Another interesting finding is that scooters strongly prefer riding on cycling infrastructure, especially neighborhood greenways and protected bike lanes, and are unlikely to ride on the sidewalk when those are present. As the degree of protection increases, however, more people ride on the sidewalk.
