I ride the San Francisco Bay Area streets almost every day, and I represent injured cyclists for a living. Those two facts inform each other more than people realize. When I'm on my bike, I ride cautiously. When I'm in the office, I see what happens to cyclists harmed by the carelessness of others. Lately, both parts of my life are pointing at the same problem: San Francisco's bike lanes are being asked to hold more kinds of vehicles, moving at more different speeds, than they were ever designed for — and the injury data is starting to catch up with what riders have been saying for years.
A Lane Built for Bikes, Filled with Everything Else
The bike lane used to mean something specific: a narrow, protected strip for people pedaling in roughly the same speed range. Now it's the default holding pen for anything with wheels and a battery — e-bikes, standing scooters, electric skateboards, delivery mopeds, and increasingly, autonomous robots. I love riding an e-bike myself, and I'm not anti-scooter or anti-technology. But I'm careful never to blow past a slower, human-powered cyclist without a courtesy ring of the bell, because I know exactly how much damage a heavier, faster vehicle can do in a collision — I've sat across the table from clients who found out the hard way.
Delivery e-bikes are a big piece of this danger for San Francisco cyclists. Some throttle-powered models used by couriers weigh well over 100 pounds and can reach speeds of 25-28 mph, which puts them closer to a moped than a bicycle in both mass and momentum, even though they're legally sharing a lane meant for something much lighter and slower. Autonomous delivery robots like DoorDash's Dot are now being tested and proposed for bike-lane travel at up to 20 mph in Bay Area cities including San Jose. And separately, Waymo robotaxis have been photographed and filmed idling in San Francisco's protected green bike lanes to pick up and drop off riders, pushing cyclists into car traffic to get around them.
What the Injury Numbers Actually Show
I don't rely on anecdotes alone, and neither should you. San Francisco recorded roughly 469 injury-involved bicycle crashes in 2024, along with three cyclist fatalities — a reversal after a year with no reported cyclist deaths. Citywide, bike-related incidents topped roughly 500 that year, with SoMa and the Tenderloin among the most concentrated crash corridors. E-bike-specific injuries have been rising sharply too: e-bike-involved emergency room visits climbed nationally from roughly 750 in 2017 to nearly 23,500 by 2022, and e-bike crashes tend to produce more severe injuries — more head trauma (TBI) and torso injuries — than traditional bicycle crashes, largely because of their added speed and weight.
It's also worth noting that SFPD bicycle crash data has been shown to undercount actual incidents, so even these numbers likely understate the real frequency of close calls and minor collisions cyclists deal with every week.
None of this proves that any single scooter, e-bike, or robot causes accidents on its own. But it does support what physics already tells us: mixing vehicles with very different speeds and weights in a lane that's only four to six feet wide increases the odds of a collision, and increases the severity of the crashes that happen.
The Legal Picture Is Getting More Complicated, Not Less
As a cyclist accident attorney, what worries me about this trend isn't just the physical risk — it's how much harder these cases are becoming to resolve fairly. A few things I'm watching:
- Fault gets murkier with every new vehicle type in the lane. A collision between two cyclists is usually a straightforward negligence case. A collision involving a delivery e-bike, a scooter-share company's device, an autonomous robot, and a cyclist can involve several potentially liable parties — the individual rider, a gig-economy delivery company, a defective product manufacturer, a scooter or robot operator, and sometimes the city itself if the infrastructure invited the conflict or increased the danger to cyclists.
- Autonomous vehicles and robots create new evidentiary questions. When a Waymo or a delivery robot is involved, the sensor and camera data those companies collect can be critical evidence — but getting access to it, and understanding what it does or doesn't capture, is a real fight. Early cases involving robotaxis and cyclists have already turned on exactly this kind of dispute over what the vehicle's data does or doesn't show.
- Comparative negligence still matters. California allows recovery even if a cyclist is partly at fault, but your compensation gets reduced by your share of fault. That makes it more important than ever to document a crash carefully — photos, witness contact info, and preserving any available camera or robot sensor footage before it's overwritten.
- Company liability isn't automatic. Just because a robot or e-bike is corporate-owned doesn't mean the company is automatically on the hook. Whether a delivery company, robot operator, or app-based platform can be held liable often depends on specific facts, contracts, and how the vehicle was being operated at the time.
I'll say plainly: this article is general information from my own observations as a rider and lawyer, not legal advice for your specific situation. If you're hurt in a bike lane collision involving any of these newer vehicle types, talk to an attorney early, because evidence — especially digital sensor data — can disappear fast.
What Cyclists and the City Should Be Asking For
Most riders I talk to aren't opposed to scooters, e-bikes, or even robots in principle. What we want is infrastructure and rules that actually account for what's using the lane:
- Wider, physically separated bike lanes on high-traffic corridors, with real room to pass safely.
- Actual enforcement against illegal mopeds and over-powered e-bikes that shouldn't be in a standard bike lane at all.
- Speed limits and geofencing for delivery robots and scooters, with consequences for noncompliance — not just self-reported safety claims from the companies deploying them.
- Mandatory data preservation and access rules for autonomous vehicles and robots involved in any collision, so injured cyclists aren't left arguing against a company that controls all the evidence.
- Public review before rollout, the way San Jose's Bicycle and Pedestrian Advisory Committee is doing with delivery robots, rather than after cyclists start getting hurt.
Bike lanes were a hard-won piece of infrastructure. It would be a shame — and, based on what I'm seeing in my caseload, a costly one — to let that space quietly become the default overflow lane for every new delivery technology a company wants to test on public streets. If San Francisco wants more people biking instead of driving, the lane has to actually be safe to ride in, not just safer to sue over afterward.
