A self-propelled driving simulator has a machine frame which can be moved by three, preferably four or more, wheel assemblies on an underlying surface. The wheel assemblies each contain at least one wheel which can move on the underlying surface and which is arranged so as to be rotatable about a steering axle. The machine frame is coupled to a cockpit which contains a seat for a person as well as operator control elements for controlling the driving simulator. The cockpit has a degree of freedom of rotational movement with respect to the machine frame, with the result that the cockpit can be rotated with respect to the machine frame about a main rotational axis, and/or wherein the main rotational axis is preferably a normal vector of the plane spanned by the wheel contact faces of the wheels on the underlying surface.
