Marchetti intended the constant to be 1 hour round trip, so a half-hour commute one-way. It’s an important distinction, since here in Atlanta the exurban commuter is clocking in at 1.5 hours or more into the city, well outside of what is considered tolerable. Multiply that by a million and you get some irritated people.
We have a lot of sprawl here and the reasons are many. Just like Dallas and LA, we have a ton of road infrastructure and zoning laws that eat up a lot of land. We also don’t have any natural barriers, like an ocean or a mountain range, to limit our expansion. Just to keep building and add another lane. Thanks for asking.
