Yeah, the ones here have multiple lanes with pneumatic tubes to transfer stuff to and from cars, and one of the tellers wears a headset like a fast food drive through. When a car pulls up, they step away from the counter and serve the drive-through window, often multiplexing to assist multiple cars. It's kind of interesting to watch, and can be (or at least feel) more efficient than going inside.

They typically only staff the drive-through when the bank lobby is also open, or a half-hour later. One of the lanes will also usually have an ATM and a dropbox for after-hours service.

TD Banks drive-throughs are staffed. I recently had to get something notarized and it was good to be able to do it without going in to the bank.
