A pedestrian steps off a curb, a shared scooter clips her at the hip, and three seconds later the rider is a block away. The medical bills land in her lap. One version of this case lives or dies on whichever bystander stuck around to give a statement. The other version runs on a data feed the scooter started writing the moment it unlocked — speed, GPS trail, battery level, start and stop — and somebody is going to subpoena it.
Both versions still happen. Which one you end up in depends almost entirely on how fast the trip data gets preserved before the vendor’s retention clock runs out.
The Old Case Ran on Eyewitnesses
A sidewalk collision used to be a swearing contest between two people who both believed they were in the right — the pedestrian swore the rider was flying, the rider swore she walked out without looking. A responding officer wrote down whatever the two of them more or less agreed on, plus the one witness who hadn’t already walked off.
That version of the case still works when there is nothing else to pull. It also loses more often than people think, because memories drift and the person with the clearest story usually wins. Juries notice who sounds more certain. Certainty is not the same as being right, and the pedestrian — hurt, scared, often alone — is rarely the more certain speaker in the room.
The New Case Runs on the Vehicle’s Own Record
A rental scooter is a sensor on wheels. It knows how fast it was moving, where it was moving, when the throttle was pinned, and when the brakes were squeezed. It knows which account unlocked it.
Most of that data streams to the operator in near real time, and a lot of it also streams to the city under a standard called the Mobility Data Specification, which more than 120 cities and companies around the world now use to manage shared mobility operations.
For a collision case, the consequence is straightforward. The rider’s version of events now has to survive contact with a timestamped speed trace. If the scooter says 14 mph on a sidewalk where pedestrian traffic was heavy and the rider says they were “going slow,” the trace wins. If the pedestrian claims a swerve the GPS doesn’t show, the trace wins there too.
A good attorney will send a preservation letter to the operator within days of being retained, because the data is the case.
Both Cases Fight Over the Same Three Questions
Whether a claim is built on witnesses or on telemetry, it ends up litigating the same handful of points. The evidence just comes in through different doors.
- Speed at impact. Witnesses guess. The vehicle logs. A GPS fix every second or two produces a speed curve that an expert can authenticate and a jury can read on one slide.
- Where it happened. A pedestrian says “on the sidewalk.” The rider says “in the bike lane.” The GPS trail puts the vehicle within a few feet of a specific tile of pavement, and a sidewalk strike reads very differently from a bike-lane one.
- Who was riding. Witness ID is weak after a few seconds of adrenaline. The account that unlocked the scooter is not, and the operator keeps that record whether anyone asks for it or not.
Where the Riding Happened Changes Who Pays
Sidewalk collisions are not a rare edge case. A systematic review of e-scooter injuries found that 26.2% of injured riders were hurt on the sidewalk, with head and neck injuries making up more than a fifth of all reported harm. Pedestrians struck by those same riders show up in the same emergency rooms, usually without a scooter to blame for the fall.
Most cities bar scooters from sidewalks outright, or restrict them to walking pace. A GPS trace that places the vehicle on a sidewalk at 15 mph is close to a per se liability finding against the rider. The older case had to prove the where. The newer one comes with the where printed on it.
Preserve the Data or Lose It
Operator retention schedules are short, and the city feeds are not built to answer civil subpoenas. If nobody tells the vendor to hold the trip, the trip can age off in weeks. A pedestrian who waits for an insurance adjuster to call back may find that the one piece of evidence that would have won the case is already gone.
Two things need to happen fast. A written preservation demand goes to the operator naming the date, approximate time, and location, specific enough that the right trip can be pulled. A public-records request goes to the city for any MDS data covering that corridor during that window. One of the two usually survives.
When Each Case Still Wins
Witness-based scooter cases still win when the scooter was private, when the operator stonewalls and the city has no feed, or when the data is ambiguous enough that human testimony fills the picture. Data-based cases win almost everywhere else, and they win cleaner — fewer disputes, faster settlements, less room for the rider’s “I was being careful” story to carry the day.
An injured pedestrian doesn’t get to choose which case they’re in. They do get to choose whether the trip data still exists by the time anyone goes looking for it. That choice has a shelf life measured in weeks, not years.
