Rate the following essay on its writing, argument, and language skills:
I believe that driverless are something that should continue being developed. Sometimes risks must be taken in order to advance in deptartments such as transportation. I believe that if we allow this to continue, it could lead to great advancements in transportation and will lead to making long distance travel much easier and much more safe. I'd like to ask anyone who is against the development of driverless cars this simple question: "Can you imagine a world where there are no car accidents caused by tired drivers or by people who are texting while driving?"

Some might say that these cars are currently too unsafe to test. I personally disagree with that idea, as it sets a bad example for future experiments. Cars themselves would not exist if they had not been tested by someone brave enough to try them. Neil Armstrong would never have set his foot on the moon if he had not been brave enough to test the rocket that had been built for his crew. If we are too afraid to try something, even if it isn't as grandiose as stepping foot on a heavenly body, then what will that be saying to the ambitious young engineers that would like to build a rocket to send the brave young astronauts to Mars? We cannot sacrifice scientific advancement for the sake of safety.

To say that the cars being currently tested are unsafe is seemingly an exaggeration in itself. For example, cars with the "Traffic Jam Assistant" have sensors equipped in the steering wheel to assure that the driver has both hands on the wheel at all times while the car's autopilot is in progress, assuring that the driver can take control at any time. This is actually something that is already quite common in airplanes. Would people who argue against these cars be afraid when a pilot puts their airplane on autopilot as well? If not, then I don't quite see why someone would be so afraid of these cars.

To say that these cars are too radical to test is just not true. These cars are driven by computers when not being driven by their human passengers. Computers are capable of doing calculations in a matter of seconds that humans might take hours to do. Some might contend that computers can make mistakes. I must rebuttle that humans make mistakes far more often than computers ever do.

Stopping development onthese cars would be detrimental to not only progress in the field of transportation, but in the field of scientific advancement as a whole. We cannot continue to fight new ideas simply because they could possibly be unsafe. Mankind did not reach the top of the food chain by running away from the unknown; We reached the top by running toward the unknown.
