Right, and that's the problem. These cities are a product of choices that Americans have made over many decades, and now they're paying the piper.

No, Americans need to choose this for themselves, but they don't and they won't. They don't move to places like this, they don't demand it of their elected officials, they instead just buy big SUVs and move into subdivisions. Americans have chosen this lifestyle, and now it's costing them dearly.
Since most people are familiar with California I'll provide this reference which breaks it down by county. First graph is adults, second is low income children 5-19, and third graph is low income children 2-4. You will notice how the high obesity rates highly correlate with regions that are difficult to walk around in and are more rural.

As another analysis, Not Just Bikes talks about this topic quite a lot. Here's his episode on strodes: https://www.youtube.com/watch?v=ORzNZUeUHAM
Reasonable on the interstate but as your driveway (nor the store entrance) are directly on an interstate, there has to be at least some stretch of slower driving bringing the average down, so the speed on the interstate section would have to be much higher to bring the overall average speed to 72 mph.
Let me give a direct example. I pulled up google maps and what is a 10 minute car prediction (2.8 mi) is also a 54 minute walking estimation (2.7 mi) and a 17 minute bike estimation (2.8 mi). Also, 33-43 minutes by bus fwiw
That does change the numbers; 10 minutes by car being 54 minutes on foot sounds a lot more realistic than 5 minutes by car being 2 hours on foot.
This sounds nice until you actually look at most of America. Cities are designed around cars. I'm in a rather walkable city and the nearest grocery store is a mile away. That's not too bad, but other places I've lived it is 5+. Buses are bad (hour+ between pickups) or non-existent. It gets difficult to do all kinds of chores, visit the doctor or whatever. Even using a bike my grocery store shopping becomes a multi-hour experience that I have to do more than once a week where a car is 30 minutes and once every week because I can carry more. The experience is completely different in a city where I would rather actually walk than take a car. I don't think this is an uncommon experience either. What I'm trying to say is that it isn't great to just tell people to start walking but rather to recognize the design and incentives places by that design. The burdens that it creates. If you want people to walk more for their commutes then you need to design cities for walking. I've lived in many places in America where sidewalks are non-existent. If you live in these places and walk you either have a death wish or a DUI. But rather, build it and they will walk.
