China’s annual driving challenge attracts dozens of hopefuls.
China’s road to mastering driverless-car technology is bumpy and full of surprises — literally. Just ask those attending the country’s top autonomous-vehicle race .
In hot and windy conditions this week in the eastern city of Tianjin, dozens of self-driving cars raced for glory. On a circuit covering an area of 10 soccer fields, they navigated through bumps, sudden turns and artificial fog. Even fake cows and sheep suddenly crossed their paths for good measure. Some teams wreaked less havoc than others.
