Rate the following essay on its writing, argument, and language skills:
When people hear the term "driverless car", they think about how they won't have to be so aware while behind the wheel. But this is wrong. Driverless cars are still a long way off from being deemed worthy for the road. There are still a number of things that can go wrong even after they are. And these things that can go wrong can ultimately stop the development of driverless vehicles.

One such example of what could go wrong is mechanical failure. In the article, it says that there are sensors all over the car. But what if these systems were to go awry? If a sensor malfunctioned, there would be a huge blindspot for the car. And that blindspot could have a pothole or a wall hidden in it. And what happens in the event that the car just goes out completely? The sensors, the cameras, even the engine goes out, possibly stranding a driver for hours in a place that they have never been to.

The article states, "If the technology failed and someone is injured, who is at fault-the driver or the manufacturer?"Most drivers take risks in their cars by texting, calling, eating, or drinking in their cars even if they aren't driverless. Then they wonder why they crashed their car into another car or tree.A lot of drivers don't pay as much attention to the road as they should. The driverless cars would still require drivers to keep their eyes on the road, and not on their phone screen. If a driver isn't paying attention when the car says that it is time for them to drive, then that creates problems. The car could stop in the middle of a freeway, either slowing down other people or getting the people inside in an accident. Then that would lead to the driver blaming the manufacturer of the vehicle for not making it safer for them and their family. It creates prooblems for both the driver and the manufacturer, and if they are not careful, the manufacturer might have to shut down their driverless cars project.

On top of what the risks are, the cost of these driverless cars might discourage people from using them completely. The manufacturer would have to build the car, put in the sensors, the computers, and the mapping. Even with the advancements in technology that we've had in the last few years, that won't be cheap to install. Then the people that buy the cars would have to replace them in the event that there is a malfunction or it is simply overused. Then there woudl be the price of the car itself when it is initially bought. People would be willing to almost literally throw away money to have a car with a few fancy bells and whistles.

The concept of driverless cars on the road can lead to serious problems for all who travel.
