I mean...this is and always has been a real thing. Except when we were in the "we have little kids in car seats" stage in life, we ALWAYS go inside. It's no slower. It's often faster. And I am 100% convinced they check your order more carefully when you're inside, because they know you can just stand there and make them fix it (which will make their life harder, so might as well get it right the first time).
I only drive through for the simplest of things, IF the line looks short. Like, I'll swing through and grab a coffee or iced tea while running errands. Breakfast is something that's usually simple enough that you can risk the drive through.
My wife made the mistake, while running our refugee charge around to soccer practices, of going through the drive through one night....at Popeyes. And yes, they totally fucked up the order. And yes, once they did, she laughed and explained "yeah...that's what we get for going through a Popeyes drive through."
