text: Driverless cars are able to steer, use gas, and use brakes by themselves. That can help less crashes by stopping drivers who are incapable to drive from driving. This means drunk drivers, drivers who fall asleep, and drivers who aren't paying attention can't cause any accidents that would and can be prevented by not letting them control the car fully. Drivers in those situations don't have to worry about who will take them home or about any problems that might have occured if it were them driving.
