Rate the following essay on its writing, argument, and language skills:
Driverless cars are a challenging and expensive aspect. Recently, a crash occurred from a self-driving car. They are a potential danger to innocent civilians. If the driver is not alert and ready, then the damage could be very harmful and costly. Driverless cars are unnecessary and dangerous.

New cars can be very costly to the potential owner. Manufacturers will assemble this product for only a select few to purchase it. The ordinary person could not afford such a high-tech item. Also, if the car turns to be ineffective, the money coming out of their pocket would multiply to repair the car. With how much money is being spent, the car would not be needed.

The aspect of how much money is being spent would cause doubt in the purchaser's mind. There are plenty of cars that are more reliable and needed, instead of being a perilous luxury. The money used for producing and buying these cars could go towards much more necessary things. In addition the title is not truthful. The driver would still need to be alert and ready for incoming traffic and potential damage and accidents. Some cars can only function under certain speed limits and conditions which poses as a risk.

Recently, a Google self-driving car was involved in an accident. This questions the ability of the car and how it works under certain conditions. Therefore, it can harm the passengers and people outside of the car. If the car notifies the people in the car if human interaction is needed, and the person does not respond, then a treacherous incident could possibly occur. The responsibility of this is a more conflicting issue.

In conclusion, driverless cars are highly expensive to the buyer. The car still requires contact through heavy traffic. If this contact is no met, then the responsibility of a crash falls onto either the individual or producer. The car poses as a risk to the passengers and any passerby. Overall, driverless cars should not be permitted.
