Rate the following essay on its writing, argument, and language skills:
Are driverless cars the technology of the future? In the article "Driverless Cars Are Coming", the author writes about the new developments and possibilities of driverless automobiles. The author also explains the potential drawbacks of the related technology. I am against the development of these driverless vehicles.

The most important issue relating to autonomous vehicles is safety. Most driverless automobiles that are currently tested are not fully autonomous. For example, Google's modified Toyota Prius uses 7 different sensors, a video camera, and a GPS reciever. Despite this technology, the car still requires a human driver at the wheel to manage difficult traffic situations. So far, there has not been a single driverless automobile that does not require a human driver for safety. The issue of safety is the main reason why driverless vehicle development is not currently practical.

The second main issue relating to autonomous vehicles is legal requirements for these vehicles. Current traffic laws do not favor the development of driverless vehicles.. Only California, Nevada, Florida, and the District of Columbia have allowed driverless vehicles to be tested on public roads; driverless cars are otherwise illegal in all states. Liability is a major factor in the legalization of driverless cars. In a situation where driverless technology fails, liability cannot easilty be determined between the driver and the manufacturer. Both liability and legal status of driverless vehicles have significantly hampered the development of these vehicles.

I am currently against the development of autonomous vehicles. Currently, all driverless vehicles require a human driver for safety, and the requirement of a human driver should be considered impractical. Secondly, the legal status of these automobiles indicates that driverless automobiles have not been developed enough for practical usage. I believe that both of these issues will ultimately prevent the usage of driverless vehicles.
