Sometimes the issue is that there's freeways in the way. Like there could be a building close enough to your apartment that it's basically just across the street. But a freeway is in between your apartment and that building so there's no possible way to just walk there.

Here in my part of germany roads that lead to freeways are built either as a bridge or tunnel across the freeway and further to some other destination. There are also bike and foot paths next to the street so crossing freeways is not a big problem
