It reduces the demand on copper too and may give them the option of running aluminum wiring.

No, it’s not that simple. All your assembles and subsystems have to be designed around a new higher voltage architecture. That cost millions of dollars. You have to work with suppliers to get a new production lines stood up. That costs money, The cost in wire is negligible vs the weight savings. But again ICE and EVs are already too heavy. 50bs of extra harness/battery weight, eh. Aluminum wire wouldn’t be used as the tensile strength is much lower and it doesn’t conduct as well as copper. It is also more susceptible to breaking from the harmonic vibrations that all rolling chassis experience.
Lets note get into how much more expensive 48V batteries are vs 12V. That hypothetical $100 turns negative rather quickly.
