The fact that all cars should be the same is logical. The selection of
negative
earth over positive earth is the question. What did GM do? What did VW
do?
Renault? Fiat? So far I haven't heard from these guys yet. GM probably
had
enough clout to become the standard all by themselves. That is if they
were
negative earth.
Another possibility is that the electronics content going into cars from
the 40's
on drove the decision, as has been mentioned, but I kinda doubt it.
