Autonomous Vehicles Lower Insurance Costs

The insurance giant Swiss RE did a study comparing human drivers with Waymo autonomous vehicles in the same zip-codes and found that autonomous vehicles generated significantly fewer insurance claims.

This study compares the safety of autonomous- and human drivers. It finds that the Waymo One autonomous service is significantly safer towards other road users than human drivers are, as measured via collision causation. The result is determined by comparing Waymo’s third party liability insurance claims data with mileage- and zip-code-calibrated Swiss Re (human driver) private passenger vehicle baselines. A liability claim is a request for compensation when someone is responsible for damage to property or injury to another person, typically following a collision. Liability claims reporting and their development is designed using insurance industry best practices to assess crash causation contribution and predict future crash contributions. In over 3.8 million miles driven without a human being behind the steering wheel in rider-only (RO) mode, the Waymo Driver incurred zero bodily injury claims in comparison with the human driver baseline of 1.11 claims per million miles (cpmm). The Waymo Driver also significantly reduced property damage claims to 0.78 cpmm in comparison with the human driver baseline of 3.26 cpmm. Similarly, in a more statistically robust dataset of over 35 million miles during autonomous testing operations (TO), the Waymo Driver, together with a human autonomous specialist behind the steering wheel monitoring the automation, also significantly reduced both bodily injury and property damage cpmm compared to the human driver baselines.

The Waymo vehicles are in San Francisco and Phoenix so this doesn’t mean that autonomous vehicles are better everywhere. Also, when we say autonomous vehicles we really mean the entire Waymo system including backup. In addition, there are some differences that are hard to account for such as human drivers use more freeways even in the same zip codes. Nevertheless, it is clear that autonomous vehicles are happening. I predict that some of my grandchildren will never learn to drive and their kids won’t be allowed to drive.
