Could Ford offer a Single Motor Drive Mode ?

IMHO, they need to. In the R1T Rivian had a conserve setting, which I find myself using 80-90% of the time. It’s worth some useful additional range. And when the cold weather season arrives having an additional 15-25 miles is something I want.

I don’t believe you can freewheel a permanent magnet motor which is what the lightning has front and rear.

You'd need to physically decouple the motor from the wheels in order for it to provide a benefit with permanent magnet motors. Rivian uses these to "deactivate" the rear motors when in conserve mode:

It would require a clutch to disengage PM motor, which ford decided against. It’s probably because of minimal range gain versus a wear item.

And Rivian decided to go with 4 motors initially. So not an apples to apples decision on ability to decouple.

Bummer... So how does the rear motor operate in non One Peddle mode when letting off the accelerator

Compared to some EVs it essentially always has a bit of regen drag present, just way more significant in one pedal.
