You probably know this, but Philadelphia is a particularly large & dense city - which is not really representative of the country at large. There was an article about 15 minute cities on HN a few days ago. Philly is a lot closer to a 15 minute city (especially if you include public trans to walking and biking in the defnition) than most other places in the country. That's a great thing, and I wish more places in the US were like Philly.
