text: Cons of the driverless cars are common sense you will nees a whole lot of sensors which cost a whole lot of money. The driver would still need to be on alert the whole time while driving. Another thing is what if the car just glitchs and there is not enough time for myself to stop. New laws will be coming some will be changing in case of an accident. What if the technology fails and someone is injured, who is a fault the driver or the manufacturer is the question.
