text: In the end I fully agree with the use of driverless cars no matter what the primary use is for. With only minimum tolerance for errors in todays technology I do not see the likelyhood of an accident due to the fualt of the car. Although, as the article states, "If the technology fails and someone is injured, who is at fault". I refute this statement just as the article did it's self by saying "Automakers are continuing their work on the assumption that the problems ahead will be solved".The use of this technology called the Facial Action Coding System is not valuable to read students' emotional expressions. Not all expressions on a students face can be readable. Some students may have a natural expressions but show it differently. How accurate are these calculations for these expressions really?
