Earlier quoted context omitted.
I think this usage is dying out in British English in much the same way as the word "auto" for car. People still speak of "mobile networks" and "auto dealerships", but they buy "phones" and "cars".
Maybe this is a regional thing, but I'm British and I'm not sure I've ever heard a first language British English speaker use the word "auto" for a car. I'd have said that was purely an Americanism.
