text: The car only uses half the amount of gas that a normal car will use. That saves the owner of the driverless car a gigantic amount of money. It is also safer for the environent. If only half the normal gas amount is being used, then it is a geat thing for the Earth. There will not be as much drilling and sucking out of the gas. That will give the Earth more time to get more gas and it will last much longer for us to use.
