text: Humans error accounts for 90% of all road way accidents the other precent is due to mechanical failure. As Google has shown with it having driven more than half a milion miles without a crash that cars are cappable of being safe, you can make the argument humans are in these cars but the car only alerts the human inside if it can not make it through the problem its self, which these problems such as accidents are caused by human error to begin with the car can not account for something that is not supposed to happen because it should not happen with all self driving cars. which leads me to my next point that it will be better for the goverment and tax dollars.
