This is an issue sometimes. It’s not great when suddenly there’s no sidewalk and you’re walking alongside a busy road. That said, I don’t think this is the main contributor. I think people are just in the habit of driving everywhere to the point where they won’t walk 15 minutes from their house to a convenience store and will opt to drive instead, and this is in neighbourhoods with good sidewalks and no particularly busy roads. People just don’t think about walking as a means to get anywhere and they’ll frequently drive just a couple of blocks if they’re going to visit somebody nearby too, in my experience anyway.
Probably part of the problem is where they make you walk, or that nobody actually plans for safe nor comfortable walking anywhere.
