      That’s not a problem that a small machine like this will fix though. The problem with EVs towing isn’t that they don’t have enough power to tow, it’s that the energy consumption goes up significantly due to changes in aerodynamics and the loss of regen braking. Petrol and diesel cars have the same problem, but can refuel quickly. EVs can’t.

      Now imagine an autonomous trailer drone behind your EV. It’s most likely going to be electric, as most new automotive things are going to be electric by now. Then there are two options:

      1. You end up with a small thing that can’t go very far due to limited battery capacity.
      2. You end up with a gigantic machine that can go pretty far, but that’s in no way cheap or easy to store.

      In the first case you might as well use your own EV to tow. In the second case you might as well just rent or buy a vehicle meant for towing. I don’t see how the economics of it are going to make sense.

        Aero is very much fixable on these things. Sure you are not going to get zero losses but you can 100% get better than the 2 to 1 loss I get when I tow my caravan with my EV currently.

        I don’t lose regen on mine when towing, where you getting that from? I cant use one pedal, but that uses the brakes so I don’t use that mode very often.

        The good old airstream caravans despite being massively fat for their size actually get better miles per kwh and they aren’t even modelled to modern aero standards.

        The other problem are caravans, particularly American caravans, are massively fat. A lot of US caravans aren’t actually towable within recommended limits by European cars.

        Why do so many people think renting a vehicle when you already own one is cost effective, or a reasonable thing to do? Especially if you won’t be using it much once you arrive at your destination.

        Whereas the tow bot can be put to work while you’re on holiday, and you still have transport.

          Are you suggesting that the tow bot takes your camper to the site and then leaves? It’s like a municipal resource?

          I don’t buy a U-Haul truck just for the occasion that I’m moving, am I?

          In a less snarky response, in case you can downscale your primary car to be more efficient and less costly, you can save significant amounts of money. In my country, weight, size, type of drivetrain and the sticker price all determine the amount of tax you pay on the vehicle. Getting a small, light vehicle instead of a big one you need for towing can definitely make sense financially, even if you are going to tow a caravan once a year and therefore have to rent a car to do so. Of course the individual circumstances really change a lot and in general people don’t do this due to convenience or the simple fact that they do this more often.

          But you also missed the point of my reply. The point is that these tow bots will essentially be a second vehicle on their own. It will be expensive to buy one, it will be expensive to rent one and it will be expensive to own one. It won’t make sense as a product, even if you can still use your car when you arrive at your destination. The economics won’t work out, I’m pretty sure of that.

      The right answer is to rent a truck. If someone has trailer/boat money, they absolutely can afford a rental for an excursion.

      Sadly, until we see EVs that can compete toe-to-toe with vehicles that can haul stuff, gas-burning trucks are going to be with us a while. Shifting from an ownership to rental economy for such things would still be a substantial reduction in emissions.

        If you want to move logistics to electric, this technology matters.

        This is how they compete.
