Check out this all too familiar sight. I shall narrate:
In the beginning of the video, the cam car moves left to "pass" the cars merging onto the highway. This is perfectly legal, and a common courtesy if it can be done safely. Around 8 seconds, a minivan decides to overtake a car, a semi and 2 other cars. They eventually remember to "keep right" after they have overtaken to let the cam car pass. Thank God somebody can drive reasonably well.
Once the cam car passes that van, there is another van camping out in the left lane, passing NO ONE. This irritates the cam car, and he passes at high speed on the right.
Then the video comes to a little car camping out in the left lane going very slowly. This little car again is passing NO ONE. Again, the cam car is pissed and tailgates, which as I have said, is VERY dangerous and very illegal. This little car should have been mindful of their rear view mirror of potentially fast moving traffic, and changed to the right lane, but they didn't. They decide to push the cam cars buttons.
Then the little car "brake checks" the cam car, again this is extremely dangerous, and extremely POINTLESS because should have kept right to begin with if they wanted to drive half the speed limit.
I am not justifying any of the behavior in this film, it is not mine, and I just found it on YouTube.
The purpose of this post was to illustrate human behavior on the roadways when "keep right" laws are not followed.
If everyone in this film kept right except to pass, there would be minimal, if any, speeding and virtually NO aggressive driving at all.
Notice that at the beginning of the video that the driver of the cam car is calm and courteous, and is only going crazy AFTER these little pukes in the left lane piss him off.
