Rate the following essay on its writing, argument, and language skills:
In the real world of today, many people crave for the technologies of the future and one of those technologies are driverless cars. Humans have always looked to the future where cars would one day be able save us in more accidents. We also want cars to use less fuel and could be able to drive us anywhere. However, we never truly look on at what it takes to build a driverless car, until we do. However, not only do driverless cars take time to make, once driverless cars are complete, there is more responsiblity that comes with the product. Driverless cars a great thing for our future because the cars can save us in moments where humans can fail, each of them will use less fuel, and drive us anywhere.

Even today, there are driverless cars andregular cars present the ability so prevent accidents to some extent. In each of today's cars, there are sensors and other gadgets that send information to the car's computer. Processing this information, cars can apply brakes to certain tires and cut the engine in faster time than humans could, if the time ever came up for it. One such car, Google's modified Toyota Prius runs such sensors, video cameras, and gps recievers to run driverless car software.

Another reason, driverless cars will help the gas prices lower all around the world. Gas prices constantly rise as more demand for it arises and the supply of it lowers. The driverless cars of the future will need as less as half the amount of fuel or lower. With cars needing less fuel, the prices will lower due to it being affordable to give to everyone. And with more fuel, cars can travel farther and to more places.

With this in mind, the driverless cars of the future will drive humans to any place needed. Some may think it impossible, but Google cofounder Sergey Brin belives otherwise. He believes the cars in the future could be used as a public transportation system, with fleets of driverless cars as public-transport taxis. He believes it can be great.

However, for a driveless car to be the greatest it can be, it first has to be driverless. The driverless cars that are currently existing today cannot claim the title of driverless. Each car will drive to the destination as required but will alert the human to stay awake and alert such that one can take over the car when nearing accidents or work zones. So that raises the question, how can we make this car truly driverless?

The technology and cars of today are not driverless yet but in time they could be. These future cars will drive humans to any destination without human assistance. Each car will run on less fuel, effectively lowering gas prices. And with its software, the car and the human will witness less accidents. Due to special software, the cars will prevent accidents,burn less fuel, and drive to any destination.
