Rate the following essay on its writing, argument, and language skills:
Three words, self driving cars. Just the idea sounds amazing. This could lead to even better inventions and help keep the world more safe. Without the chance of human error, self driving cars could help change the world.

Someone might bring the point up, "What about if someone had a wreck? Or if the driverless car ran into construction?" That seems to be a relatively easy fix. At first the driverless cars may be a little scary, in the way that there will still be driving themselves, but as the driverless car begins to expand, there would hardly be any accidents or problems at all. If the world designed a perfect system as to where cars could drive all by themselves, they can make timing very efficient and keep all the cars on the right path.

As the article states, "The cars he forsees would use half the fuel of today's taxis and offer far more flexibility than a bus. No one likes to get on a crowded bus with a bunch of sweaty and creepy strangers. The cars of the future could change this though. With how technology is rising, and how much money we put into researching more, these cars could go a very long way. If we can fit a computer into our pocket, what's going to stop us from making a super computer out of a car?

Now while so many roads will have to be redone, it could save a lot of money. There are so many car wrecks a year, because of human error. The cars of the future would limit this though, as they control themselves and can be much more alert than a normal human driver. In the long run, we would be saving much more money if we just redo all the roads, and allow smart cars drive for us.

In hindsight, smart cars are a very good idea. Just the fact that you would have to pay half as much for gas than you do right now, is a great point. Also, the cars will be more alert than a human could ever be, with all the sensors and gadgets it could use to keep you safe. These cars will change the world.
