So where do you 40 mpg'ers live? Can we find some consistency? What about the type of commute? Stop and go? Small town? City? ...

If you have a choice of route, take the one with the most (up to a point) hills and valleys. A long downhill (or uphill) without some relief cannot use the electric assist as efficiently.
...Do this
only if it has the same or fewer full stops on the route that can not be anticipated or avoided. Full stops are more of an FE hit that the grade changes.
.. Also, if you have a choice between a freeway longer route and shorter surface highway route with only a few stops, take the highway
provided it will permit you to slow down without commuters, tailgaters and the associated freeway madness. A major problem on freeway commutes is that even if you open up a following distance for improved anticipated responses (see below), someone will switch lanes and fill it in.
Regarding stop and go, or even slow and accelerate .... learn to anticipate! Most people drive only relative to the car ahead. Learn to anticipate the actions of the car three or even four ahead, and gradually react to their actions before the cars between you to avoid stops or slowdowns.
BTW -- Commute details, 32 Mi one-way, 900 foot elevation change in Cascade foothills. Two-lane rural highway and suburban major streets with route selected for minimal full stops. Different routes for to-work and from-work based on route elevation profiles.
