A critical issue in the coming adoption of autonomous cars will be how liability is assessed and assigned by insurance companies.  When an autonomous car crashes, who is to blame?  Does liability lie with the human for not overriding the system?  Or does liability reside with the car manufacturer, or even the Tier 1 supplier of sensors?  Volvo is thus far the lone manufacturer to state that it will bear responsibility when one of its vehicles crashes in autonomous mode.  If autonomous cars are to become ubiquitous, the car manufacturers, regulators, and insurance companies will have to develop a framework that all stakeholders can buy into.
