The electrical wiring in cars is Conway's law manifest in copper.
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.
