Rate the following essay on its writing, argument, and language skills:
I do not think that driverless cars are necessary. As we know, a lot of drivers now aren't responsible while driving manually. How could they handle an automatic car? I also feel that not only will this car be very expensive to perchase, but learning how to use the car will cost a lot of money as well. Those who have been driving cars manually would need a lesson on how to control these automatic cars because it is completely different from what the whole world is used to. It would be like driver's school; therefore, that would be pretty expensive.

To begin with, cars now are already very advanced (sensors, gps, cars that can be charged, etc.) There are even sensors to help the driver on the steering wheel. Secondly, automatic cars such as these are illegal to drive is a lot of states, as someone could be injured or killed if the computer-cars fail. I don't believe driveless cars are any more safer than manual cars for this reason.
