text: The last reason I think we should consider driverless cars is efficiency. In the passage, driverless cars would have sensors that cause the car to apply brakes on individual wheels and reduce power from the engine, which in general allows for better response. Imagine if you were driving and got distracted, something bad could happen really fast. That would never happen with a driverless car since the main goal of the car is to get to any destination. The efficiency comes in to where the person in the driver seat could take over at any time in case of something in the way or just bad traffic issues. There are many ways for the car to notify the driver to take over such as vibrating seats or sensors to tell the driver what to do.
