While flat towing a GT40 200 miles strikes me as a spectacularly bad idea, unless your car weighs less than 1,500 lb, your adventure may be in violation of state or local laws (in addition to the ones of common sense). Brake lights, integrated brakes, breakaway brakes, safety chains, lighting,mirrors, etc. etc. may be required and regulations should be checked. I'd also think that having a "light operator" in a towed vehicle is illegal as well.
