Rate the following essay on its writing, argument, and language skills:
I think driveless cars is a great idea in some ways. We certainly would have some complications and arguments. Driveless cars has some positive aspects such as using have the fuel we use today in taxis and offer more flexibility than a bus. Some other positve things is GM has developed driver's seat that vibrate when the car is in danger of backing into an object. The driveless car uses laser beams to form a constantly updating 3-D model of the car's surrounding. There is also some negative or not so good parts of a driveless car. For example, incase of an emergency, we have to take over the "driveless car". There is no playing around which means we have to be focus at all times to be prepared for accidents or road construction. If there a accident, the argument will be if its the drivers fault or the manutacturer fault. That situation will be in a big debate. The cars can steer, accelerate, and brake themselves, but all are designed to notify the driver when the road ahead requires human skills, such as navigating through work zones and around accidents (7). Who knows if everyone in the future will have driveless cars. I think they would be useful for only certain people and not so much of everybody.
