text: The cars themsevles would cost a fortune to make but "smart-roads systems"(3) would cost too much money for anyone person to pay. Now the car itself would be too much money because of the need of so many sensors. With an estimated guess, there would have to at least 11 different types of sensors to be place in one car. Even with thousands of dollars going into the driverless cars, they still have not found a way to have a completely driverless vehicle. Different cars call for different driver's assistance. Some "make sure the driver keeps hold of the wheel,"(7) while others will send a signal to the driver such as, vibrating the seat, announcing to driver that they "should be prepared to take over"(7), and others have flashing lights. Which means that in no way is this car driverless if it some how requires the drivers help with driving.
