Rate the following essay on its writing, argument, and language skills:
Diverless cars aren't a good idea. Even though Genral Motors developed a special test track to determine is these cars are working or not , when this car is sold the might still be a defect.

At first the were constructing a smart road that took a lot of magnetic sensors, which cost a lot to do. So they started a smart car. to make this car they need alot of sensors. This car took alot of time an work to manufacture. The most important part of this Toyota Prius was to mimic the skill of the human at the wheel. These sensors were advanced to detect response to danger of " out of control skids or rollover". The information from the sensors can cause the car to apply brakes on individual wheels and reduce power from the engine. Even though it allows better response for the car, what about the people in the car that might get hurt inside the car.

This diverless car might be good for some, but some might think that people should still take caution in there their driving because if people use this car more, people might get to use to the car stopping on its on . They might forget how regular cars work.
