Autonomous Cars vs. Motorcyclists: When Sensors Fail to See You
Deadly Blind Spots on the Road
In July 2024, a motorcyclist was killed near Issaquah, Washington, when a Tesla in Full Self-Driving mode rear-ended them on I-90. Investigators later confirmed the vehicle’s sensors had failed to recognize the motorcycle in time to brake. Just six months later, in January 2025, another Tesla struck a motorcyclist in Seattle. Logs reportedly showed the car only flagged the motorcycle seconds before impact.
These two crashes—separate but hauntingly similar—revealed a dangerous blind spot in autonomous systems: they struggle to “see” motorcycles. And the problem isn’t confined to Washington. In April 2025, a Tesla in Autopilot mode clipped a motorcyclist in Arizona during a lane change. The rider survived, but the system’s failure to recognize the motorcycle in an adjacent lane underscores the same troubling pattern.
Why Motorcycles Are Especially Vulnerable
Autonomous vehicles depend on cameras, radar, and LiDAR to classify objects in real time. But motorcycles present unusual challenges:
- Their slim profile makes them harder to detect than larger vehicles.
- Their movement is more agile and variable, such as lane-splitting or quick merges.
- Their visual and radar signatures differ based on rider position, speed, and environment.
The result: motorcycles are often misclassified as debris or simply registered too late for evasive action. In both Washington crashes, riders were visible to the human eye, but the systems failed to act until impact was unavoidable.
Who Bears Liability?
Product Design and Testing
If a system cannot reliably detect motorcycles under predictable conditions, the manufacturer may face product liability claims for design defect. Plaintiffs may also allege negligence if developers failed to properly train or validate algorithms on motorcycle scenarios.
Fleet Operators and Deployment
Companies that deploy AV fleets may bear responsibility if they launch in motorcycle-heavy regions without safeguards or if they set aggressive operational parameters. Courts may find reckless deployment if known detection weaknesses are ignored.
The Human Factor
Semi-autonomous systems like Tesla’s Autopilot still require a human driver to intervene. If the driver fails to respond, liability may be split between human error and technological failure.
Access to Evidence
One of the greatest challenges for injured riders is access to AV data—sensor logs, video, and calibration files. Manufacturers often treat this as proprietary. Without reform, victims may face steep hurdles even when the technology was clearly at fault.
Insurance and Compensation Challenges
Traditional auto insurance doesn’t fit neatly into AV cases. Some policies exclude autonomous operation, while others lack clarity on how to apportion liability among manufacturers, operators, and drivers. Victims may find themselves caught in multi-party litigation just to recover medical expenses and lost wages.
What Motorcyclists Should Do
While riders can’t eliminate AV risks, they can prepare for both prevention and legal recovery:
- Maximize visibility. Fluorescent clothing, reflective tape, and auxiliary lighting improve odds of being detected by both humans and AV sensors.
- Record the ride. Helmet or dash cams provide crucial evidence if AV logs are contested or withheld.
- Document everything after a crash. Photograph the vehicles, scene, signage, and witness information immediately.
- Preserve AV data. Work with an attorney quickly to issue preservation letters compelling retention of sensor logs and system records.
- Choose experienced counsel. These cases hinge on technical evidence and understanding the law. Motorcycle accident attorneys familiar with AV technology can leverage expert analysis to establish liability.
- Advocate for stronger standards. Riders’ groups should push for detection benchmarks requiring AVs to prove motorcycle recognition accuracy before deployment.
The Road Ahead
Autonomous vehicles promise fewer accidents overall, but motorcycles expose the technology’s blind spots. The Issaquah fatality, the Seattle strike, and the Arizona lane-change crash show that the systems struggle with two-wheeled vehicles in ways they do not with cars and trucks.
Regulators may soon require manufacturers to certify motorcycle detection capabilities, insurers will need to adapt coverage, and courts may demand broader disclosure of system logs. Until then, riders remain vulnerable—not because of their skill, but because the future of driving doesn’t fully see them.
