3D Express Coach

It was unveiled at the 13th Beijing International High-tech Expo in May 2010. A trial was scheduled to begin in Beijing's Mentougou District by late 2010, however the project was not given authorisation by the district authorities - the technology was considered to be too immature, and further trials will not be put out unless a concept is proven to actually work.
