text: In the article it mentions people testing out and making assumptions to these self driven cars. One statement caught my eye when saying "They worked surprisingly well, but they required massive upgrades to existing roads, something that was simply too expensive to be practical." That is one example of why we shouldn't be putting self driven cars on the road, they're going to be expensive and always needing an upgrade, what if you're driving, well your car is driving itself, and you run into an issue while on the road with others out there, could the car malfuntion and cause you to lose your life?
