Rate the following argument fragment on its writing, argument, and language skills:
Evidence: Looking at paragraph 4 it states that,"Google's modified Toyota Prius uses position-estimating sensors on the left rear wheel, a rotating sensor on the roof, a video camera mounted near the rearview mirror, four automative radar sensors, a GPS receiver, and an inertial motion sensor." From this quote, you can already see how complex a driverless car needs to be in order to run efficiently. All of these gadgets have to installed and all of them are very necessary. According to the author in paragraph 4, it also claims, "The most important bit of technology in this system is the spinning sensor on the roof. Dubbed LIDAR, it uses laser beams to form a constantly updating 3-D model of the car's surroundings." If the LIDAR malfunctions, then the car has no information on its surroundings. It would be virtually impossible for a driverless car to work without the perfect execution of all these devices. I believe that there is too much room for error.
