On a more serious note, there's a raft of published SAE papers available on the topic of fuel economy / emissions reduction that cover coasting strategies in some detail (inc. when they are advantageous and when they aren't). They make for interesting reading, although maybe not as entertaining as internet videos....

Going up the hill, rather obviously. Same fuel used however the downhill is driven. Rather obviously.
