I'm guessing that the no-queueing is also due to the nice low-tech pencil-and-paper voting solution we have. I have no idea how many voting machines are at a typical US polling place, but I'm sure they can't serve nearly as many people in parallel as the Australian style little cardboard booths, where any decent-size polling place will have dozens of people voting in parallel. The bottleneck is at the place where they look up your name in a giant book (never a computer!) but I've never had to wait more than a few minutes there either.
