Methods and systems for monitoring use, determining risk, and pricing insurance policies for an autonomous vehicle having one or more autonomous operation features are provided. According to certain aspects, accident risk factors may be determined for autonomous operation features of the vehicle using information regarding the autonomous operation features of the vehicle or other accident related factors associated with the vehicle. The accident risk factors may indicate the ability of the autonomous operation features to avoid accidents during operation, particularly without vehicle operator intervention. The accident risk levels determined for a vehicle may further be used to determine or adjust aspects of an insurance policy associated with the vehicle.
