'Course the author is assuming an internal combustion engine. Presumably
with a hybrid, the coasting actually CHARGES the batteries, thereby
increasing gas mileage. I'm not even going to get into external combustion
engines...

I dont buy it, it isnt a gasolene consumption issue, when coasting in
gear the engine is not moving at idle speed, the extra rpms are a drag
on the transmission and lower mpg, the trans also has more drag being
in gear. He is only thinking gasolene not drivetrain friction loss.
