This episode of The MacNeil/Lehrer Report looks at the pluses and minuses of driving electric cars. These battery-operated vehicles fell out of fashion in the United States at the turn of the century, but an Arab oil boycott and the threat of penalties by President Jimmy Carter on gas-powered cars has led to a renewed interest. Robert MacNeil and Jim Lehrer present a history lesson on electric vehicles, before speaking with engineers, car makers and conservationists about the chance of an American resurgence.
