In fact, the best thing to do is to use the gaps between cars to absorb speed differences so as to allow ALL traffic to flow more smoothly
I agree with you, and I find that this is easier to do in a manual because the acceleration is instantaneous. I have found that I don't have to accelerate as hard if the response is immediate, versus delayed. I don't have to brake as hard because I start slowing as soon as I back off the gas.
With most automatics, the off-pedal cruising speed is 20 to 25 mph, which means that driving any slower than that requires riding the brake. From behind, a slow, steadily moving automatic appears the same as one which is stopping, or stopped. So they create a situation in which drivers behind a steady 15mph automatic vehicle have a harder time estimating traffic speed - which leads to the inevitable traffic accordion.
