Rate the following essay on its writing, argument, and language skills:
Now a day, car is one of the best choices that people use

for travelling. Is it going to be better if the cars that you are using right now can be driving indepently, without the driver. Is it going to be helpful and easier for our mankind.

In my oppionion,the diverless car can be easier for us to travel.Based on the artical,the google has had cars that could drive independently,their cars have driven more than half a million miles. They also have a GPS which can help the drivers to fond out their location,sensors on the left rear wheel, a rotating sensor on the roof, a video camera , four automotive radar sensors and an inertial motion sensor. The developing of

the cars can improve sensors and computer hardware and software to make driving safer.

On the other hand, their were no cars developing

completely driverless. The accident can happen every moment, this means that human driver must always be careful and alert when they are driving.
