I'm going to take a guess that the coolant pump should be on and
circulating coolant to the motor and controller. When you spin a PM
motor, even when it is off, it still generates some amount heat due to
eddy current losses. This would be especially true at sustained highway
speeds.
When you put the car in "neutral" you aren't really disconnecting
anything mechanical. (The motor still spins.) You are just signalling
the motor controller not to do anything, like use the generated power to
charge the battery (regen).
However, if you can actually turn on the vehicle, and the wheels
would roll correctly, why would you need to have it towed?

I know the operator manuals on my Leaf and Spark EV say they can't be towed
with 4 wheels down but why not can't you just put it in neutral or disconnect
the motor wires? On all my conversions I've had no problems towing wheels
down. Both say to use a tow dolly
