Why is this about survival? My commute to work is 20 miles. I drive because it's convenient, quick, and practical. I would survive without a car. I could walk for 6+ hours, work for 8 hours (snacking while I work), and then walk another 6+ hours back home. Or I could pitch a tent in my office parking lot and just live out of it during the week. It would be shitty survival, but doable, right?

It's absolutely possible traveling without a smartphone. I've done it plenty of times before smartphones became a thing. But smartphones make it so much easier.
