What about not moving, and just increasing the engine speed? The only thing motion is doing is intruducing ram air through the radiator. I have not seen one, but it could be a logical symptom of a water pump that is not flowing adequately. Is this happening after something else had been done to the car, or just come on all of a sudden? Is this overheat occurring with only the A/C on, or does it overheat at idle with A/C off? You say you have not noticed any coolant leaks, but make no mention of coolant level, I would have to assume it has been checked and is full, with adequate coolant concentration.
