These motorists proved they arent the brightest sparks - by destroying their cars after crossing jump-start wires. The motoring mishap resulted in damage that meant both cars were write-offs. The incident in Columbia, South Carolina, saw silver Jeep owner Andrew Jernigan connect jump-leads to 21-year-old friend Delaney Mills red Volkswagen. Their pal Marc Coty saw the whole thing. Coty explained: Delaneys Volkswagen stalled on the street, so Andrew pulled his Jeep up to her car to jumpstart it. ON
