I get what you are saying, and i completely agree with you in relation to the second vid. On the other hand I don't have a problem with the first, there is a lot of traffic and unlike over here they use their horns all the time, so the horn on the Humvee would not stand out. The driver is not being impolite, nor is he causing accidents, he is just telling people to move out of the way, because if they get caught in a traffic jam that will give an insurgent, or a suicide bomber, time to set up. That will put not only themselves at risk but also all of the cars and people around them at risk. Therefor I don't have a problem with what the driver is doing on the first video. The second video is just stupid.
