My brother-in-law who is a professional firefighter DID NOT rig up any spark plugs just inside the edge of his exhaust pipe outlet, and those plugs were NEVER connected to a line leading to the windshield washer reservoir, which was MOST CERTAINLY NOT filled with gasoline, nor was any of this apparatus connected to a switch on his steering column. Therefore he DID NOT EVER back his car up to any dried up cornfields in New Jersey and set them aflame when he was young and foolish.
