Not sure if you are in the US, but here what you are saying is absolutely not true for most people. Most of the country is so incredibly car centric that there’s absolutely no way you could bike 30 miles across a city. And then in most places the public transit is incredibly bad.

For example, I am a 40 minute, 30 mile drive from the city center. Most people in this area would consider that a reasonable commute. It would take 2 and a half hours to bike that distance in melting Florida heat and heavy aggressive traffic. It would take 2 hours by a succession of busses.

If I wanted to live a nice bikeable distance from the business center, I would pay dearly for it home price.

It didn’t have to be like this, but at this point we are so committed to suburban car-centric sprawl that there is now way back for most of the country and things like walkability, bike friendly and rapid public transit are going to remain luxury goods.
