A boom in car sales has caused traffic mayhem in many of China's major cities. One company wants to improve the situation by putting even more people on the road. But rather than add more cars, Shenzhen Huashi Future Parking Equipment is developing a massive "straddling bus." Cheaper than a subway, the partly solar-powered behemoth will span two lanes and carry up to 1,200 people in a carriage raised 7 ft. above the roadway, thus allowing cars to pass, or be passed, underneath. Passengers on the new bus should rightly expect to feel above it all. The company is awaiting government approval for a trial project in Beijing. If that comes through this year, test runs could begin by the end of 2011.
