Self-driving cars will reduce auto accidents and result in “significantly lower” insurance premiums for consumers, according to a new report from Moody’s Investors Service. “Self-driving cars will likely force auto insurers to rethink their business models,” the report said, while noting “widespread adoption of this technology is decades away.” However, the building blocks of self-driving cars, including features such as automatic braking, adaptive cruise control and lane-departure warning, are already rolling out onto many vehicles. These accident-avoidance technologies are likely to have an “immediate” effect on insurance premiums. “Auto insurers will face higher auto repair costs from embedded cameras and sensors which are often located in or near bumpers,” the report said.
