Abstract: Input data comprising dynamics data taken from at least one actual dynamic vehicle, and position data of the at least one actual dynamic vehicle, and data relating to the environment of the at least one actual dynamic vehicle is acquired and at least the dynamics data is utilized by computer game software to generate a user controlled dynamic vehicle. At least the environmental data is converted into a form suitable for display on a display device. User input means provides control signals for the user controlled vehicle to facilitate competing in the same environment as the actual dynamic vehicle as reproduced on a display device before the user. More particularly, the input data is converted into a graphical form to display the at least one actual dynamic vehicle in their actual environment or as modified to accommodate the position of the at least one user controlled dynamic vehicle.
