Like a literal, pleasant, long walk kinda like a journey like Shrek?

EDIT: DayDreamGaming on Youtube seems to have a gold mine of these type videos
Take out all the people and creatures trying to kill you along the way and I feel like a walk down the intended route from Goodsprings to New Vegas would be fun enough and fairly pleasant. Otherwise, it’s a survival game nightmare I wouldn’t win, no matter how you slice it.
And if you’d consider Yooka-Laylee open world, the full first book you enter would be fun to stroll all over in for a short while. Especially since the majority of the enemies look like little pushovers.
