Maybe this is an opportunity to test out different battery chemistries that may initially move into their cars. Alternately, the magnesium chemistry could be cheaper than lithium but less energy-dense, hence not a great choice for the cars. Or it could be inappropriate for vehicle use for a number of reasons including safety, cycle lifespan, etc.
