Nice. It'll never happen. Like the underground football stadium and air-conditioned cycling track.

Given the sloth of the locals, I can't imagine many people walking briskly for an hour and a half to visit shops at each end. It's obvious people would drive. Do you think that will be taken into account when planning the roads???

Can I suggest one improvement? They build a hill in the middle and theme it as an alpine village. Qatar needs more hills.
