text: Do smart cars still seem cool? I'll leave that answer up to you, but take everything i have said into consideration. Smart cars may be the future, but the way they are now is too dangerous. There are too many complications including lack of safety, lack of automatic driving, and lack of laws needed to operate a smart car. So, is a smart car really smart?     Nowadays, technology and science became one of important parts in human life, it makes life runs easier. With human's intelligent, technology is improved day by day. Many things are dicovered, or invented that we don't even know about their appearances. One of them is the Facial Action Coding System also known as FACS, which technology could identify human emotions was created by Dr. Paul Eckman. In my opinion, I think this techonology is useful, especially in order to read the emotional expressions of students in a classroom.
