For example, in the article it states that the smartroad sytems work surprisingly well, but that they require a massive upgrades to exsisting roads, that was simply to expensive to be practical. Driverless cars would require the upgrade of not only a part of Indianas road but the whole U.S. and the world. Which is a tremendous amount of money that would be needed to upgrade all the roads. Driverless cars do not only need upgrades in road to be safer and work better, but the car itself needs alot of expensive technology to operate correctly and safely. For example, a driverless car needs spinning sensor on the roof, dubbed LIDAR, it uses laser beams to form constant updating 3-D model os the car's surroundings, and so much more is needed for the driverless car to mimic the skills of a human at the wheel.
