It seems like this is great for producing a car as cheaply as possible. If one of those 3 parts (front casting, rear casting, structural battery) is damaged in a wreck, it seems probable that the car would be totaled by the insurance company. It's not clear how a damaged casting could even be repaired. In an ideal world, cars would be driving themselves and not crashing into one another, of course.
