Insurance, liability & autonomous vehicles

On Sept 15th, California’s Dept of Insurance held a public hearing on autonomous technology insurance issues. Representatives of both the legal and insurance fields were invited to provide insights and commentary. The question and answer period touched on both shorter and longer term insurance. In the shorter term, how do (will) insurers currently rate vehicles with semi-autonomous features like adaptive cruise control, lane assist, parking assist, accident avoidance, and driver fatigue detection? Longer term, what type of insurance product will ultimately be most appropriate to cover AVs? Commercial products liability? Something else?  Further, is data collected by AVs an insurance issue and if so, how should insurance be involved?
