And nobody ever tows a vehicle that is not "rated" to tow? And unlike ICE vehicles where the transmission probably does not lubricate when driven from wheels, nobody has pointed out a mechanical reason a EV can not be towed.

Mechanical reason # 1, EV's have motors connected directly to the wheels, if the wheels turn, so do the motors.

So I sent an email to Tesla to ask about their new pickup truck and if it will be towable 4 down behind our motorhome. First response from them was , what do you mean by towable 4 down ? Next email I explained how I tow my F150 behind our motorhome and wanted to know if the new cybertruck will support that. Their response was that none of there current vehicles could be towed 4 down as it would burn out the motor(s) , but they didn't have any information on the capability of the new truck. I responded that how could they be taking orders on a new vehicle when they don't even have specifications on that its' capabilities are. I imagine it will be the same-- no 4 down towing.

But there are hybrids that can be towed 4 down

So I learn. It would take some reprogramming to tell the toad to roll with no foot on the go pedal. And some to have the first part of the proportional brake controller to regen, then when more brake would start the friction.

Not that's getting into territory that will never happen.

There's no way to get a toad to receive communication from MH, much less be able to communicate back to the MH.

I'm talking just about the toad being set to charge at some unknown charging rate.

Excuse me? No communication? With my dumb pickup towing a dumb trailer, using technology that has been around for decades, I step on the brake pedal, the trailer brakes come on. Harder on pedal, pickup slows at faster rate, more voltage to trailer brakes. No communication?
My understanding of toad brake system, the more brake applied to MH means more brake applied to toad. I can see the computer in the toad reading Voltage on brake wire. Say 0- 1V, freewheel, 1.2-3.5 regen, and above 3.5 start increasing the friction brakes.
And have not even got into wireless. How many have a wireless cameras mounted on trailer? Just aim the camera at the gauge panel.

Both our EV’s have neutral positions on the selector. You can select it on the fly and the car literally free wheels. However. The cars need to be on.

If the neutral circuit is there, just need to toggle it by a signal from MH throttle position, so goes to neutral as soon as the engine is signaled to pull. And as the the throttle nears WFO, the motors re-engage, and power up. Of course, if the MH driver is wanting to go faster than he has horses he might not have any battery power at the end of day.

I don’t think it will be hard to set up an EV for towing four down. I do think it will be hard to enable regenerstive breaking.

Any of the front wheel drive EV’s can be towed on a dolly. They can be left off when towing on a dolly.

Regen braking is exactly that. No throttle, regen applies to load to match coast down FMVSS requirements. Apply the brake, and they system applies greater regen loads... until you exceed regen loads and friction braking takes over.
