By all accounts, driverless cars are coming soon and will transform civilization. They said that about the Segway too, but this prediction seems a bit more plausible.

Many cars will arrive at church parking lots empty, which means many plates of deviled eggs will go bad in the back seat, but this is better than the carnage that might have ensued during the era of human-driven cars.
