Why had transportation made so few improvements? people and goods did not travel far. the technology was not available. the new transportation was too expensive for the common man. transportation had improved in europe but not america?

Unlike in Europe, America has States. The jurisdiction of transportation development lies on the heads of the states. Since decision making is decentralized, it will take a lot of communication efforts in between states to finalize a transportation project that will link the different places in a more efficient transportation system. In Europe, decision making and budgets are centralized and therefore improvements and implementations on transportation are more achievable and faster.
