Would be funny to have a ‘mm Cu / FTE’ scaling law.
The ohm*meter^3 is the unit of electrical resistance.

Is there a name for Wh/m or W/m (of Cu or C) of loss? Just % signal loss?

There's already conductive graphene 3d printing filament (and far less conductive graphene). Looks like 0.8ohm*cm may be the least resistive graphene filament available: https://www.google.com/search?q=graphene+3d+printer+filament...
Are there yet CNT or TWCNT Twisted Carbon Nanotube substitutes for copper wiring?
For those unfamiliar with Conway's law, I am arguing that how the car companies have organized themselves--and their budgets--ends up being directly reflected in the number of ECUs as well as how they're connected with each other. I imagine that by measuring the amount of excess copper, you´d have a pretty good measure for the overhead involved in the project management from the manufacturers' side.
