First, to give credit where credit is due, I found the video above via a Cracked article: http://www.cracked.com/article_19004_6-things-that-annoy-you-every-day-explained-by-science_p2.html
It gets mentioned in the second item where they explain what shockwave jams are. The video is of a man demonstrating and explaining how driving with a space ahead of him and maintaining it, rather than speeding up to catch up to the traffic ahead of him, it breaks up the traffic jam. Because he’s for the most part maintaining his speed and his distance from the car ahead of him he’s not braking a lot. This means the people behind him don’t have to brake either. The other way it helps prevent traffic jams is that the gap he maintains gives people a chance to get on and off the highway. So people are able to get where they are going rather than having to slow down as they run out of room to make their exit due to people not letting them in.
This video isn’t going to make anyone laugh but it’s a really cool example of how a) 1 person can make a difference and b) being polite helps everyone around you. 0326-11
