Car Straddling bus system - a permanent solution to traffic jams?

Well what do we have here? It is the future is closer to us than we can imagine. This May the Shenzhen Hashi Future Parking Equipment Co Ltd. introduced a very novel idea that brings a futuristic idea to combat a very current problem in many leading metropolitan cities of the world.
What we have here is basically a buss that is elevated above the road so that it can allow most of the vehicles that currently are on the road to pass from beneath them without any reduction in speed. Although it seems that technologies to achieve this sort of thing are far off from now, the fact is that this system is supposed to go under construction by the end of this very year! What wonders would this do to Pakistan's busy roads and railways. Essentially the Pakistani Government wouldn't need to invest in new infrastructure and the load on the current infrastructure wouldn't be increased as well. Plus, this is a very green technology as well. Pakistani regulatory authorities, if you are listening, it sounds like a win-win here! Oh, and since you are here, where are the CNG buses you promised us a while back?
