'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...

Interesting, I didn't know about the injectors shutting off when
coasting in gear. With a carbureted engine, you would save some, but
it is much harder on the brakes.
I had a motor home that wouldn't lock in low, it would just jump to
2nd no matter the selector position. That was downright scary in
Colorado brake fade was a certainty, not so much if, as when. As soon
as I got to the flat lands I pulled the valve body and put one in from
a 4wd truck. then it would stay where you put it, and descending
grades was almost fun.

On the other hand, with a standard trans, always coast into red
lights on level ground. I'm going to idle in neutral with the clutch
out, waiting for the light, so it sets up the maneuver nicely, it
saves the throw out bearing.
