I didn't watch it on CNN, but I have read an article or two about it. For the really hard-core hypermilers, it ceases to be about saving money and turns into something like a sport. Turning without braking first could be a little hard on tires and suspension parts, depending on how hard and how fast of a turn we're talking about. I take tight turns going pretty fast quite often, but I just do it for fun. They do other stuff more off the wall, like turning the engine off and coasting on hills and when slowing down.
