My main criticism with the piece is it muddies the waters about what "pulse and glide" is (discussion of BSFC often includes a P&G description, as this one does). It essentially describes "Pulse and DFCO", not Pulse and Glide. DFCO necessarily occurs in gear, with engine braking slowing the vehicle as a result. DFCO is not a true glide. A true glide occurs in neutral and will out-distance DFCO. Engine-off gliding will beat DFCO every time in terms of better fuel economy.
Fair enough. But I am reluctant to recommend driving in a way that is illegal for most of my readers. Rolling around in neutral is actively frowned upon here, and - I would have thought - in most other places as well.

Its a neat little gadget, but the average driver won't use one.
It can be easily adjusted over a wide range, so is quite suitable for 'average drivers'.

Scan Gauge? Well, FuelSmart is far easier to use, far cheaper, and suits cars for which a Scan Gauge is not available. Locally, that's literally millions of cars.
