SAN ANTONIO -- The city of San Antonio has plans to add 4,000 more dockless scooters by the end of the month.

• Officials concerned there could be a rise in injuries
• City introduced pilot program to balance rider and pedestrian safety

The San Antonio Fire Department said with more scooters comes more injuries.

"This is nothing alarming to us. It's something you expect to happen; we're just tracking it now. It's just getting that empirical data that you can see it and we can say, 'This is what we need to address. This is where we need to address it. What's the best way to get there?'," said SAFD spokesman Joe Arrington.

Since October, when the department started tracking scooter injuries, there's been 54 emergency calls.

"Those injuries range from minor scrapes and bruises to trauma alerts where a patient needs to be transported, whether that's falling off and breaking an arm or hitting a head," Arrington said.

Misty Leung is no stranger to scooter injuries. She was an avid scooter rider before hitting a bump in the road and shattering her leg in three places.

"When I hit that bump, it's like I hit a wall. I flew so hard. I was embarrassed because I hit the ground. People were actually walking over me because I'm sure they've seen it a million times,” said Leung.

The city introduced a pilot program in October that will determine how to balance rider and pedestrian safety. The program will hopefully give the city answers in April on what the extent of injuries are and how to address them.

"We needed time to evaluate it, that way we could come back to city council at the end of the six-month pilot program with some more revised, more refined regulations that will address more of the impact in what we're seeing," said Center City Development and Operations Director John Jacks.

Jacks said there is 'no cap' on how many scooters are allowed within the city limits. There's an application process companies go through that charges a $500 application fee and $10 per scooter in the fleet. There are around 8,100 scooters now, with a total of 12,000 planned by the end of the month.
