I think part of the appeal of walking is that you're away from screens. You're in action (even if it's as simple as putting one foot in front of the other), not just passively receiving sensory data.
As Baudrillard put it: "Travel was once a means of being elsewhere, or of being nowhere. Today it is the only way we have of feeling that we are somewhere. At home, surrounded by information, by screens, I am no longer anywhere, but rather everywhere in the world at once, in the midst of a universal banality - a banality that is the same in every country. To arrive in a new city, or in a new language, is suddenly to find oneself here and nowhere else. The body rediscovers how to look. Delivered from images, it rediscovers the imagination."
That is a great observation. I have realized that I enjoy bike rides and driving because it forces me to be off my phone, unlike even walking, or of course sitting at home.
