I'm sure there are places where it is difficult to walk anywhere. Those are not the norm, however. I don't recall any places like that in Seattle.

Most parents with kids try to pick places to live that are reasonably kid friendly. Real estate people know that, and advertisements emphasize things like walkability and distance to schools.

Seattle is definitely out of the norm. Even Northgate, which doesn't have sidewalks in places, has roundabouts on the collectors to discourage speeding. I grew up in a poverty-level suburb and you were walking miles away on cramped sidewalks even to get to a grocery store. When I grew up cars couldn't accelerate that quickly so it wasn't that scary, but these days cars can travel at > 60 mph on collector roads between lights.

This is just not a take that squares with how it is to live anywhere in America outside of the denser urban cores and some shallow radius of the suburbs around them. Perhaps it was correct at some time in the past before the suburban expansion of the post-WWII era. Perhaps Seattle is different from the overwhelming majority of the United States and is uniquely walkable or upzoned. I would not know since I have not been there before.

In the United States today it is the norm for middle and upper middle class parents to raise their children in car-dependent suburbia. Particularly in the last half century, most new residential developments have been exactly this. The defining features of these places are sprawling circuitous developments of detached single-family homes, massive parking lots, impassable highways, and strip malls.

If you'd like an example, please come visit Loudoun and Fairfax counties. I grew up in that area. They are some of the wealthiest counties in the country, a common destination for families in the DMV, and you will see how much walkability and proximity to schools that money has bought them.
