Look before you leap. This one fundamental rule has saved people from jumping into dangerous holes, onto stuff, into things and so forth, for thousands of years. Now why cant people listen to their natural instincts and apply that on the roads? I see so many people nowadays that indicate, start to move into the next lane, and THEN look at whats there. Only to have to dangerously swerve back into their lane to avoid that car/truck/bus/motorcycle. What has happened to the sequence of this survival instinct?? Leap and then look?
