While major e-scooter firms encourage users to wear helmets, there are few regulations requiring them.
More than 1,500 people have been treated for injuries from using battery-powered electric scooters in the United States since the craze began in late 2017, a Consumer Reports survey showed.
The nonprofit consumer magazine said its tally, based on reports from hospitals and emergency officials, is incomplete and does not include four reported fatalities linked to e-scooters. Still, it counted 1,542 cases of emergency treatment for scooter-related injuries after contacting 110 hospitals and five agencies in 47 cities where the two biggest scooter companies operate.
