'Drivers race through expressway toll gates as their wireless wallet pays the fee, while GPS updates in half of South Korea's 17 million registered cars tell them how many minutes delay they can expect and how to take a faster route. Public buses are fitted with shrieking dashboard road-nannies that help drivers stay on schedule. Millions of passengers seamlessly transfer using the ubiquitous T-Money travel card, finding their next bus or subway train on up-to-the minute electronic schedules.'
