The car is climate controlled, has a stereo, I can have water/food in it without needing a backpack or carrying anything, and it's sitting in a comfortable seat while I'd find a super long walk like that uncomfortable. I could use headphones while walking but something about walking feels like a constant distraction if I'm trying to listen to something. And if I'm in a car, I feel like I can go anywhere I want on a whim, while if I'm walking I'll just want to get it over with and only stop somewhere if it's directly on the way.

If you find walking 20 mins uncomfortable and don’t think you have any health conditions I’d recommend seeing a doctor.

I don't mind walking if I want to, on a trail or something, but not if I have to. I guess I'm just not used to it and don't like it enough to make it a habit.

It depends what you're walking through! I'll walk for hours on a beautiful nature trail or a pretty, safe cityscape with interesting sidewalk-addressing buildings.

I won't walk for 5 minutes sandwiched between a fast road strip-mall parking lots, industrial facilities, or open fields.

Lol what’s wrong with walking next to an open field?

It's exposed (to the sun and the wind) and it's dull. Inviting pedestrian environments need a sense of enclosure. Can be sidewalk-abutting buildings, can be trees, can be parked cars, can be all three. And they need stuff to look at that isn't monotonous.

Fair enough, but you couldn't do 5 minutes of walking by an open field?

That kind of thing usually occurs in low-intensity suburbs/exurbs where I can just drive.

For a five minute walk? With having to start and park the car, you might not even make it faster.

Walking the small path between a highway and some fields was literally how I got to high school.

Because he's American. By and large, they love cars.
