As electric scooters have rolled into more than 100 cities worldwide, many of the people riding them have ended up in the emergency room with serious injuries. Others have been killed.
With summer fast approaching, the numbers will undoubtedly grow. Cities are continuing to grapple with how to manage the two-wheeled vehicles that riders adore but motorists and pedestrians scorn.
There are no comprehensive statistics available but a rough count by The Associated Press of media reports turned up at least 11 electric scooter rider deaths in the U.S. since the beginning of 2018.
Data on injuries or fatalities linked to scooters is hard to come by because the industry is so new.
