text: The driverless vehicle is also very expensive. There is no point in paying more money for this irrelevant toy when there are cheaper options. "Radar was a device on a hilltop that cost two hundred million dollars. It wasn't something you could buy at Radio Shack," is a clear example of the uneccessary payments. "These smart-road systems worked surprisingly well but they required massive upgrades to existing roads, something that was simply too expensive to be practical," is another quote that depicts the financial aspects. The computer-driven cars cost too much money.
