I could see this working if it was hardwired to the lead vehicle for data over a wire and that would also include a safety tether. Since it seems to be aimed at EV owners, give it a big ass battery and allow it to share power with the lead car to extend the range of the pair. If the trailer give you longer range on your road trips, let you have one plug to charge both vehicles at each charge stop, and had a safety tether and did the data wired rather than wirelessly, I could see some rich folks springing for it. As advertised it sounds like a bad joke from a b rated 90s scifi movie
Even then it seems far less practical than building a PHEV where the range extender really only is used during towing. There really isn’t a practical gain here except that it’s another thing a manufacturer can sell, repair, and upsell you on. Diesel electric locomotives still exist and until rails are fully electric will continue to exist.
