why not both? make it a thing you rent when you need it that also extends the range of your EV when you are on a long road trip without making you haul around extra batteries/weight during your normal commute. If they did this with a data cable and a safety cable and allowed the caravan to share power with the tow car I think it’s actually a neat idea
I think the big advantage here is you could rent the doohickey, rather than buying a massive battery bank you’ll only use a few times a year.
The doohickey could still be attached physically to the car. It’s probably cheaper to add a hitch than the necessary tech for this to work remotely.
I can definitely see a use case for a powered dolly for vehicles with poor range or low towing capacity.
