In the future, will self-driving cars be our designated drivers? To those of us who enjoy a spirited spin along a twisty back road, an off-road adventure in a 4x4, or even a good old-fashioned stoplight drag race, a self-driving car has all the appeal of a self-eating cheeseburger. Unless, of course, we're able to throw a rolling interstate cocktail party, simultaneously toasting the marvels of technology and lamenting the obsolescence of the human race. Or at least peacefully sleep it off on the way home from Cousin Jethro's bachelor bash. All joking aside, Popular Mechanics does not advocate, condone, or encourage drinking and driving of any kind, at any time.
