Once a manufacture designs a car that is optimized for shortys, everyone will follow suit. The current designs are solely based on your standard stick type or saddle batteries. And that limitation is creating a bottleneck with layouts, hence all manufactures end up with the same designs. Imo, at the point they allowed saddle packs, the battery dimension criteria should have been thrown out, as long as it made the same voltage. I don't think we should be dictated with rules based on the technology level of the 80s.
