It's worth posting. You'll notice the list has a big omission: there's no discussion at all about ideal acceleration rates. Mostly because it's one of those big "it depends" (TM) situations. EG: auto vs. manual transmission; what are you going to do after accelerating (cruise? glide?)

It's probably true to say that jackrabbit starts are wasteful, but some people might take that to mean that glacial acceleration is the most efficient. Which also isn't true for all vehicles/situations.

And maybe I missed this one on the list, but;
Never Downshift
In general, yes, better to coast! But sometimes downshifting can save fuel: If you've come into a situation where you need to slow down (can't coast), you can use DFCO (deceleration fuel cut off) if your RPM is high enough. Save a few drops rather than braking while idling.
