It depends on the infrastructure as well. I'm about a 7 minute drive from my local commuter rail but it's essentially unwalkable as that 7 minutes is basically along an interstate. I do take the commuter rail if I'm going into the city 9-5 on weekdays but that's very rare.
Right.
I find this whole topic reductive in general. Specifics matter quite a bit. I don't disagree with some of the article but it feels very gloomy compared to suburban life I see around me.
Yeah, it depends on your definitions I guess. I'm certainly not in classic suburbia. I think ESRI says I'm in an exurb. In any case, I'm certainly not walking anyplace except down to the river or to a couple adjacent neighbors or conservation land within a 100+ acres total. Where I grew up was similar. This is considered urban by the US census by the way.
Sounds anything but urban to me!
