Any form of enforced 'limiting' would be seen as a 'driver aid' and not allowed.

The perfect technical gizmo would be a solid state accelerometer (the sort of high tech gizmo that's used to control missiles by inertial guidance systems) it could control acceleration in a straight line and cornering speeds plus braking in fact it could control everything! A 3-axis acceleromter could detect the movement of the car in all directions and connected into a speedo could prevent any electronics and motor 'abuse', it could even make everyone have equal car performance (as equal as the gizmo could be set and calibrated to be equal) and they don't cost very much... but they're not allowed and most likely nobody wants them either.
