text: The main reason that driverless cars would be a danger to society is simply that they are electric, and malfunctions occur in technology frequently. It is stated in paragraph 7 that the vehicles would be equipped with "driver's seats that vibrate" or "flashing lights on the windshield" to warn the driver of upcomming terrain that the car would not be able to maneuver on its own. The problem in this is that if a battery were to go out in the flashing lights or the vibrating seats malfunctioned, the driver would not be alerted of the forthcoming danger, and a crash would be innevitable.
