Automation helps drivers in a tight spot

When Liu Chang bought his first car last year, he thought it would boost his social life. Instead, the car all but ended it.

"With the competition for parking so intense where I live, I usually have no choice but to tear myself from a party and drive home," said the 22-year-old Beijing University of Technology student.

His home is in Cheniandian Hutong, part of a labyrinth of alleys in Beijing's Dongcheng district.
