Yup its on its way..
This isnt anything new, but its a topic that hasnt been discussed.
For those that were clueless about this, here's whats up.
Withing a couple of years we will start seeing these on cars.. The transition will be gradual, but eventually the entire electrical system will be built to that voltage. Higher voltage = less required amperage. Thus smaller awg wires and such..
Many cable/air/fluid components will be switched to small electrical motors (brakes..)
And we'll be able to have a motherload of electronics. 12v is really being pushed to its limits..
