Los Angeles - With the oldest ever candidate and the first black nominee the upcoming US election already has a lot of firsts. Now add another: drive-through voting.

For a few hours Tuesday night voters in car-crazy Orange County can perform their civic duty without leaving the comfort of their automobiles at eight electronic booths set up in a southern Californian parking lot. The booths are also available for voters to register on the last permitted day before the November 4 election.
