Exactly they probably saw all those stupid eco modders trying this and thought, "Oh hey lets do something but less haphazardly". But then issues started to arise and it fell flat.

I feel it could work but it would need to be a hybrid capacitor and glass-mat battery, so you still cut weight essentially in half, and the capacitor can provide instant high amperage for a starter, whereas the battery portion can be used for long term storage and other electronics and to give the alternator a barrier to charge the capacitor. But at that point with that much R&D lithium ion is going to come so far in the next few years that's going to be the future of the 12V car battery....
