The document said it generates electricity during towing when the front wheels are on the ground, not the rear wheels. Interestingly it says it will do this even when the high voltage system is turned off, which I assume they are referring to pressing and holding the power button for three seconds which emergency responders do to shut down the HV system and also deactivate the airbags. As to what the risk is I don't know since it seems unlikely anyone will be touching the car while it is being towed. Typical electronic devices store energy in capacitors and such for a while so there is a slight shock hazard even after you unplug the device, but I'm not sure how much energy could be stored in the system while towing that would make it dangerous once stopped.
I was wondering what would happen when the clarity was towed and left in ready to drive mode and also in trans in drive with front tires on the ground. After sime distance the engine could start if needed to get rid of excess electricity and also if the battery was low it would be getting charged by rolling down the road. Im not suggesting doing this just wondering what you all think would happen.
 
how would the car know its being towed? Wouldn't it be the same as coasting in drive? Obviously you couldnt go in reverse or long distances.

The car seems to be quite intelligent. Perhaps smarter than a 5th grader.
Ask Honda, they provided information in the manual that says towing it as you suggest will damage the drivetrain. They may just know more than the rest of us.

Try it and let us know how it goes. You’ll need to install a base plate on the vehicle to attach to the tow bar. I don’t know of a manufacturer that makes one since Honda states that the Clarity cannot be flat towed. You’ll also need to install a supplemental braking system to be legal. Also, try towing it on a tow dolly with just the front wheels off the ground. It would be a great vehicle to tow behind the motorhome without having to put in on, or in, a trailer.
