Abstract
A computer includes a processor and a memory storing instructions executable by the processor. The instructions include to rank a list of minimal risk maneuvers for a vehicle by expected risk score; for each minimal risk maneuver, update a distance from a present location of the vehicle to a respective end location, wherein each end location satisfies a minimal risk condition corresponding to the respective minimal risk maneuver; in response to a first anomalous condition selected from a set of anomalous conditions, determine a distance limit based on the first anomalous condition; then select the minimal risk maneuver ranked best for the expected risk score from the minimal risk maneuvers for which the respective distances are below the distance limit; and then instruct the vehicle to perform the selected minimal risk maneuver.
