text: For instant saftey. The sensors , are the most important object in the car especially the roof sensor. What if the roof top sensor completly just stop working, there would be nothing anyone could do. If any of the senors went out on iany driverless cars the owner couldn't even use his/her car. The driverless cars could also shout down at anytime out of nowhere and there would be nothing to do for it. These driveless cars can also take off on there own when the driver isn't even ready to start to take off and go. Companies are just making these cars becuase they think that they are cool and that some peolpe out in the world are thinking that there cool too. They also know that they can get lot's of big money of these driverless cars. Driverless cars should not go pass the law where it says that "traffic laws are written with assumption that only safe cars has a human driver in control at all times." Driverless cars are not safe at all and a human diver isn't in control of the car, the car is doing it all on its on. "If the technology fails and someone is uinjuried, who is at fault ... the driver or the manufacturer?"
