it beats sense. some one overtakes u at 150 kph. after disturbing u with multiple flashes. only to find him waiting in the next traffic light . just as the rest of the drivers. if u are traveling from Doha to industrial area or akra u reach at the same time because u wait for each other at the signals. some one teach these people its useless to rush unless its an open road like Saudi road. don't they use there common sense?
