It's only through the construction of highways that suburbs can be accessible. There was a great study done to show that the cost of highways is mostly subsidized by the inner city, not the suburbs themselves. Are you intentionally confusing separate issues? An hour away from the city is an hour away from a city, infrastructure can change the distance you can travel in an hour (e.g in countries with high speed rail, it's not uncommon for people to commute over 100 miles, that'd be a very long commute anywhere in America). The highways extend the amount of land that's available for commuters, maybe cities should pay for them as the highways make it possible for cities to get away with inefficient zoning.
