Yep, but on a car you might have moments where the voltage drops below 12V
(e.g. idling / slow traffic when the heated screen plus headlights are on).
I imagine it's tricky to get 12V out of 11V (say) whilst able to deliver
enough current to keep a disk spinning (say). Of course I'm sure it's been
done, I've just not seen published details of schematics etc. anywhere
before!
