1. A method for optimizing a set of vehicle-dependent control parameters for use in controlling a vehicle, the method comprising establishing an initial set of vehicle-dependent control parameters, the vehicle-dependent control parameters comprising car-specific values for control functions including at least one of braking, accelerating or steering; computing a first set of vehicle control values based upon the initial set of vehicle-dependent control parameters; computing a first set of motional data for the vehicle at a first time; controlling movement of the vehicle based upon the first set of vehicle control values; computing a second set of motional data for the vehicle at a second time later than the first time; computing a revised set of vehicle-dependent control parameters based upon a comparison of the second set of motional data with the first set of motional data; computing a second set of vehicle control values based upon the revised set of vehicle-dependent control parameters; without user intervention, iterating through these operations by replacing the initial set of vehicle-dependent control parameters in the establishing operation with the revised set of vehicle-dependent control parameters for each successive iteration until an optimal set of vehicle-dependent control parameters is computed; storing the optimal set of vehicle-dependent control parameters; and using the stored optimal set of vehicle-dependent control parameters by a control system to maintain a computer-controlled car along a path in a computer video game.
