Autonomous Vehicle Accidents: Where Does Liability Go?

As autonomous driving features become commercially available, the legal doctrine of traffic accident liability is facing a fundamental shift. Existing legal doctrine has been designed with the driver's duty of care at its center.

However, when the system performs a substantial portion of driving decisions, the very content of the care that can be demanded of the driver changes.

Candidates for liability are divided among the driver, the vehicle manufacturer, and the developer who created the driving software. The conclusion differs depending on whether the cause of the accident was sensor misrecognition, the limits of the decision-making algorithm, or the driver's failure to intervene.

In practice, securing data from the accident recording device effectively determines the outcome. Who preserved what data and when is the key to the initial response.

If product liability doctrine is applied, who bears the burden of proving the defect is also an issue. Software defects differ in nature from traditional physical defects.

In future damages lawsuits, disputes over data access rights are likely to proceed before the merits of the case itself.

Until legislative discussions are settled, clearly defining data provision obligations at the contract stage is a realistic response.
