bluetwo: pulse and glide was invented decades before hybrids hit the market.

As dcb points out, it just takes a bit more fussing in a non-hybrid.
In a hybrid, lifting off the throttle kills the engine. Then you finesse throttle position to ensure you're truly "gliding" (no regen, no battery assist). In a non-hybrid, you kill the engine / shift to neutral.
