I agree with this observation. I cringe when I hear other comments talking about people driving through traffic trying to smooth out traffic waves. I am very suspicious about the claim that this speeds things up for anyone.

People accelerating hard and braking hard is not good for traffic, but if there is some guy moving slower than possible on a highway with a lot of commuters, many people will need to change lanes to avoid that obstacle. That is not good for traffic either.
