That's good advice, and what hypermilers attempt to achieve in traffic like this. Our term for it is "Driving Without Brakes", or DWB, meaning we try to maintain constant forward movement by picking the right speed to let us not use our brakes at all, or come to a stop. The whole idea is to conserve momentum.
