text: So if they did have a machine that can read facial expressions but can't read emotions that they are hiding isn't a very good machine. They just need to build a machine that can do both. All because someone can be something else then what the machine picks up. So they need something that can do both so it can be right. All because of the reason someone don't show a whole lot of emotions. Plus the person can be lying to the machine and the machine picks up that you are happy but really you are not. My argument for the development of the driverless cars is that we should have them. These cars should be allowed to be made, they can become really helpful to people. They can also provide really good safety features. The diverless car will help the environment, it will spend less of our natrual resources that we use. These cars will change the way our future will look like.
