A woman in her 50s was seriously injured Friday when she came off a scooter in the Henry E. Kinney Tunnel in Fort Lauderdale, fire rescue officials said. The crash happened just before noon as she and another person were riding Lime-S scooters on the sidewalk next to the northbound lanes of the tunnel, said Battalion Chief Stephen Gollan. “She was coming down the tunnel, saw something on the sidewalk, and that’s the last memory that she had,” he said. She was taken to Broward Health Medical Center in serious condition, Gollan said. She had broken a bone and suffered a concussion, he added. The Dockless Bike Share and Scooter Share, also known as the Dockless Mobility Program, is the city’s new shared mobility program. It began Nov. 1 and allows users to unlock, rent and ride bicycles, electric bicycles and electric scooters from virtually anywhere by using a smartphone app. There were more than 40,000 rides recorded in the first month, officials said But some skeptics have questioned user safety. Alexis Gutierrez, 14, sustained serious injuries in a hit and run collision with a car at 4 a.m. Dec. 1. “We’ve had a series of accidents on them and we’re tracking the number of accidents on them now,” said Gollan. “When I pulled the records around the time he had been hit, we were at an average of one a day.” The scooters, which are powered by a 250-watt electric motor, can reach a top speed of nearly 15 mph, and can travel nearly 40 miles before needing a recharge. Drivers must be at least 18 and have a driver’s license.
