What point?
30mpg is not inefficient by current averages. The fuel economy of a range extender becomes less important the less it is used. Put another way, the fuel economy of a range extender becomes more important the more it is used.
Since we are talking about very rare instances of use, and the inefficiency inherent in a device that only has a single application (pusher vehicle), it can actually be more efficient to run a series configuration generator. Efficiency is not relegated just to the realm of fuel economy; there is efficiency of one's time, efficiency of utility, efficiency of money... the consideration of all resources is important. For those who frequently need extended range, a pusher may very well be the perfect solution.
As IamIan pointed out, energy produced by a generator need not go through the losses associated with charging a battery if the motor is demanding the energy directly.

I tend to be indifferent to the upstream power source, as my main consideration is cost per mile. My time and money is a primary concern as long as the environmental consequences of my choices appear to be relatively inconsequential. It turns out electric is cheaper per mile than fossil fuels, and when the vehicles themselves come down in price, this will make financial sense. It just happens that Oregon primarily generates RE.

There is no reason a microcontroller can't shift (including neutral/coast) and control throttle efficiently...

As I said, a pusher very likely makes the most sense for some people, but as you point out, perhaps they should have just bought a Gen 1 Insight. The complexity, safety issues, and single purpose nature of a pusher just makes it impractical and inefficient for most.
