Pakwheelers' version:
-driving at a constant speed
-driving at roughly 2000 RPM with a light foot
-occasionally putting it in neutral, and shut off the engine at traffic lights
All the while ignoring DWB (the building block of hypermiling), DWL (constant speed actually contradicts hypermiling), and underestimating amount of fuel consumed during fast acceleration (its much more than people think).
Driving at 2k RPM is really dependent on the situation. For example, say you are going at 2k RPM @50 km/h in an ES1 automatic on a fairly flat road. In reality, you are wasting more fuel than necessary; the car is in 3rd gear. It will only upshift at this speed into 4th (fuel saving gear in this situation), if you lift of the accelerator. Also, for some reason people give more importance to driving at 2k RPM than DWB; DWB requires eyes on the road, not on the tach.
Gliding in neutral gives the best results when used for longer distances, with the engine off. Gliding for a couple hundred meters at <70 km/h with the engine on doesn't give good results.
Other than pulse and glide, the greatest savings come from DWB during local driving, and DWL during highway driving. NICE-ON and FAS are secondary techniques.
