MILWAUKEE (CBS 58) — A Milwaukee woman is recovering from serious injuries after friends say she was hit by someone riding a Lime scooter on the sidewalk. Now, city officials and Milwaukee residents are once again raising questions about the future of Lime scooters in the city.

One reckless decision can change everything.

On Tuesday morning, a 71-year-old woman, who does not want to be identified, was hit by a person riding a Lime scooter on Brady Street. The rider then fled the scene.

"I see it a lot over here because I see people who are cruising. I see it on the Oak Leaf Trail,” said Olivia Cranston, who works near where the crash happened. “They’re going incredibly fast.”

Friends of the victim said she suffered fractures to her left wrist and elbow and will need plates inserted in her arm.

“People are getting critically injured because they’re getting hit by a full-force vehicle. That’s really going to hurt. And if you are old, that’s really, really going to mess you up," Cranston said.

It's not the first serious incident reported.

Last month, a popular Milwaukee bar owner was injured by a person riding a Lime scooter on the sidewalk and required spinal fusion surgery. The rider was charged with a felony.

“He was run over in front of a bar. He’s a bar owner," Milwaukee Ald. Bob Bauman said.

According to a report provided by the Department of Public Works, Lime scooters issued more than 17,000 warnings to riders in the City of Milwaukee during the month of June. Those warnings included improper parking and riding scooters on sidewalks.

“I fell over when I saw those numbers. For one month? I had to do a double take. Is this really a month?” Bauman said.

Eighteen people were injured in scooter-related incidents during June, with injuries ranging from minor to severe.

Bauman said he wants more transparency from Lime. He has proposed increasing fines for riders to as much as $200.

"They’re able to detect these violations electronically, through their platform. So why aren’t they being more aggressive about sidewalk riding?” Bauman said.

In a statement to CBS 58, a Lime representative wrote, in part, "Noncompliant sidewalk riders are warned or banned, not fined. It is our continued goal to keep sidewalks accessible for all Milwaukeeans."

The statement went on to say, "We are working with DPW to take a multifaceted approach to mitigate sidewalk riding and improve parking, including tracking infractions for sidewalk riding and parking violations."

Some Milwaukee residents said they simply want to be able to walk safely.

“I’d like to see more transparency, but in a way, I just want them gone," Cranston sa
