Moving the battery to the other side of the car (on the dominant tire side, right rear tire) and setting it as far back as possible is exactly what should be done for a consumer car. I think that is what was on their minds. I have seen a Lincoln (something or another) car with a trunk mounted battery, but I don't remember exactly how it was set up. I don't think the back seats folded down eithor, making it a safely contained area for battery fumes with a trunk mount. Ford was trying to be more "practicle" in their design I think.
