A British research team analyzed the accident risk of electric scooter users and found that the risk of traumatic brain injury and internal organ damage was significantly higher than for motorcycles or bicycles. This was attributed to the low helmet wearing rate and structural characteristics of electric scooters (small wheels, lack of suspension). The research team proposed safety enhancement measures such as mandatory helmet use, stricter speed limits, and design improvements. They also emphasized the importance of safety management, noting that female users are at a higher risk of serious injury than male users and that the proportion of child users is also high.
