Image shows a recently unveiled design concept for a "straddling bus," which lets cars drive underneath. The concept was the brainchild of the Beijing-based Transit Explore Bus, who took their design to the just-concluded high-tech expo. Powered by electricity, the straddling bus could replace about 40 conventional buses, holding 1,200 to 1,400 passengers, and achieve a speed of 60 kilometers per hour, according to the engineer of the project.
