Rate the following essay on its writing, argument, and language skills:
I believe that driverless cars can potentially change how the world operates and that they can completely revolutionize the world of public and even private transportation. Driverless cars, with the right modifications, adequate moderation, and an alert human capable of taking control of the car in the rare event of a technology failure within the vehicle, can be even more safe than humans driving cars.

In the United States alone, there are numerous occasions in which people have been severely injured or even killed in car crashes that were caused by people who have fallen asleep at the wheel, driving while intoxicated, or tending to other needs while driving. With driverless cars, a vast majority of these examples of car crashes could potentially cease to exist.

In the article "Driverless Cars Are Coming" it states that "Their (Google's) cars have driven more than half a million miles without a crash." With the technology that is present in the world, it is possible to develop a car that is truly driverless. Also in the article, it says that "He (Sergey Brin) envisions a future witha public transportation system where fleets of deverless cars form a public-transport taxi system. The cars he forsees would use half the fuel of today's taxis and offer far more flexibility than a bus." Although these cars are not available right now, it is, without a doubt, possible for them to be available to the public in only a matter of time.

Driverless cars are truly "the future of transportation." Driverless cars, within a certain number of years, can be available to the population and can be even safer than alert humans driving. Driverless cars truly have the potential to revolutionize the world of transportation.
