For lots of America alternatives don't take that much investment. Creating a safe bike network would be relatively cheap and is feasible in large swaths of suburbs.
Due to the aforementioned car dependence: points of interest are further apart from each other than in other cities with solid cycling infrastructure (in Europe for example).
Enormous car-lots several times larger than the buildings that they serve for example, sprawling 6-lane roads that take 20s to clear a junction on a slow moving bicycle, these things contribute to it being infeasible for more poeple.
Connecting the bike lanes is not a problem, though people will fight it tooth and nail because they wan't all infrastructure spending to go to cars... hence, reinforcing the issue, because when all you have is a hammer...
Yes, they are further apart than they need to be, but they still tend to be within relatively short cycling distance. At certain times cycling is even faster than driving due to gridlock traffic, even in suburbs. For example, this very moment, because the main way through town is clogged with parents picking their kids up from school.
I think a majority of the problem is cultural and/or political. I know people who take a longer drive over a shorter bike ride (due to gridlock traffic).
Bikes can reach remarkably far in flat areas if the infrastructure is there. And with a folding bike you only need 1 bus as a range extender to go really far. However lots of money is relying on both those things not happening.
