I dont think I have ever seen a national and/or his family attempt to cross a busy highway.... unless of course its in his Cruiser - ergo - no need for ANY footbridges - its like the film "Death Race 2000" out there some days!! I'm sure in the "secret book" that all Qatari's have that we expats arent allowed to look at - you know, the one that ellicits hate against foreign workers and invites nationals to come up with more and more ways to make our lives a misery out here, that there are points allocated for "hits" for different nationalities and different levels of mobility.
