Yup, got that, even attributed Mr Sharkey in my article. Guess I'll be more explicit and say that an electric pusher on a daily-driven ICE vehicle is somewhat backwards. An EV is the 95% solution, and a pusher trailer is the 5% cure (WRT most people's annual mileage profile). An electric pusher trailer or something like this electric 5th wheel project;

reduces the utility of the base vehicle for marginal gains in performance, while
A gas pusher for an EV increases the utility of the base vehicle with huge gains in performance, though so far the result has been no better efficiency than simply driving a dedicated highway gasser instead. As with many ecomodder-style projects, it's more for the fun of trying out a wild idea than practical payback. I maintain that for a single-vehicle household that does not fit with a Volt or Tesla, an EV with an ICE pusher is the one solution that provides fuel-free daily driving and uncompromised road trip ability.

Now someone may prove me wrong with an electric pickup bed trailer that has perfect control for pushing around the efficient family hatchback, I just see this idea as much more problematic than the proven pushing of EVs by ICE.
