Rate the following essay on its writing, argument, and language skills:
The idea of having driverless cars is interesting. The thought of not having to worry about the dangers of being on the road, when your car is the one doing all of the work for you. There are many positives to having the driverless car, but there are as many negative as there is positive.

Sergey Brin, Google cofounds, envisions a future with a public transportation system. He imagines this system to become a form of a public taxi transport. Brin's idea allows the vehicles to use half the fuel that taxis use today and it offers more flexibility than a bus. Google created a car. Google has had cars that could drive under specific conditions and their cars have driven more than half a million miles without having a crash. Now, ideas of the driverless car were sparked up by the idea in movies. Companies have tried to make the driverless car work, but no one has made a driverless car that doesn't need the assistance of the driver, yet. Companies started to question if it wasn't the car that wasn't making their project work and maybe it was the roads that the cars were driving on. In the late 1950s, General Motors created a car that could only run on a special track that was embedded with electrical cables. The cables sent a radio signal to the front of the car. The smart road system worked exceptionally well, but the upgrade to new roads would simply be too expensive. There are many car manufacturing companies working on the progress of making driverless cars happen, but the cars still need the drivers to be on alert to watch out for pedestrians, other motorists and etc.

Our form of transportation is evolving right before our own eyes and its quite exciting to know that by the time I'm in college, driverless cars won't just be an idea that I thought would have been nearly impossible to accomplish.
