text: In the passage in paragraph 3 it says, "These smart-road systems worked surprisingly well, but they required massive upgrades to existing roads, something that was simply too expensive to be practical." That means it would cost a lot of money to fix every single road just so a driveless car could go. And that means it has to be a debate on if everyone argrees with it. Im sure everyone does want to keep spending their money on a taxi and they have bills to pay. That's like annihilating all of the vehicles in that area.
