They can point it out as much as they like, they're still wrongitty

Sure. That's not how a switch-mode regulator works, at all.

Why ould you want to do that? hard enough to get the bloody wimmen to
fetch the beers as it is!

Sorry lads, can't offer you lot a beer... bloody GB's locked the door

How many beers in the fridge?

Christ I had a 1979 Jaguar that had an auto fuel cutoff(1)

(1) yes it worked(2)
(2) no it wasn't an unintended consequence of lucas being unable to
reliably supply power to the fuel pump :-)

So for all intents and purposes, the amount of additional fuel consumed
when the headlights are turned on is immeasurable, so this "lights on =
more fuel" business exists in theory only.
