You are combining two separate issues KW. There is traffic congestion, and there are dangerous road users. Traffic congestion can only be solved when fewer people use the roads and/or road capacity is increased. But as for the dangerous driving culture in Qatar, I don't know how that will be solved. I think some people are just born and bred to be rude, aggressive, dangerous drivers who will overspeed, cut people off, drive up the hard shoulder etc. I will admit however that the traffic congestion makes bad drivers here behave worse out of sheer frustration, but these are the same drivers who will drive at 160km/hr up the north road even when there is no traffic.
