Sure, but that's not the point from my perspective. From my perspective the point is that players only request to take Rests when it makes mechanical sense for them to do so. If there's no mechanical benefit, then they don't.Does an in-game character ever feel tired? Is actual PC tiredness reflected in any way mechanically in D&D?
If the DM narrates a six-day road journey, no one ever says "Oh, by the way, obviously my PC is going to get tired during those six days of travel, so I want to take two Short Rests at 11am and 3pm, and then a Long Rest each night" in order to "play their character". Nope... those rests are just ignored completely and becomes an assumed thing that just happens during the "You've traveled for six days" narration and not something the player-as-PC needs to announce.
The only time players actually announce that they want to take a Short or Long Rest is when the game mechanics require that announcement by made in order to refresh. Which means the rests the players make are due to a metagame consideration and not a narrative one.
I mean not that it matters either way. Whether a Rest occurs because the player genuinely emotionally feels their character is just worn out, or because they have a bunch of game mechanics they want to refresh for the next leg of the journey... the results are the same.
