Seriously, this is the future that China's envisioning: huge friggin' buses engulfing smaller cars on the road. Despite the silly picture and the eccentric "3D Express Coach" branding, this cunning project by Shenzhen Huashi Future Car-Parking Equipment actually makes sense. The idea is to make use of the space between regular-size cars and bridges, thus saving construction costs as well as minimizing congestion impact by allowing cars to drive underneath these jumbo buses. Fancy hitching a ride? You better start planning your move to Beijing's Mentougou district, which is where Huashi will commence building its first 186km of track at year's end. For now, enjoy the Chinese demo video after the break (translation text at source link).
