I disagree on the fuel savings... If you are coasting in gear, the injectors are shut off and no fuel is consumed. If you are coasting in neutral, the engine is idling, and you are burning fuel. The difference is how much engine drag is caused and does it prevent you from maintaining speed.
Shutting off engine as you coast in neutral is a really bad idea as also lose your source of vacuum for braking.
