Abstract

A method includes, responsive to determining a vehicle is operational, receiving vehicle data associated the operational vehicle. The method receives driver data associated with a driver of the operational vehicle. The method receives environmental data associated with a location for the operational vehicle. The method calculates a drivability score based on the vehicle data, the driver data, and the environmental data, wherein the drivability score is a measure of optimal driving conditions. Responsive to determining the drivability score is below a drivability score threshold, the method performs an action based on the drivability score.
