you can often help clear it out just by slowing down to the average speed it's moving I'm of a similar belief. However, I've run into self-proclaimed professional traffic engineers who insist the best thing is for you to tailgate the car in front of you as closely as possible. The provided justification was that the more tightly traffic is packed, the sooner people can reach their exit & free up space on the road. I still don't buy it.
