Rate the following essay on its writing, argument, and language skills:
Do you think a car that could drive itself is very safe? Of course not, people that take drivers test need to be able to pass to drive in public ; If there are driveless cars then these test would not be needed and the roads would be less safe. These drivelress cars are also not safe because they are not fully able to drive themselves, they have a sensor which could have technical difficulties, and if the technology fails it would bring problems to the owner and manufacturer.

The cars need an alert driver at all times, Google has had cars that can drive themselves under certain conditions since 2009 but need a driver to take over during times. In the text it says "they still alert the driver to take over when pulling in and out of driveways or dealing with complicated traffic issues," but if the driver is not alert a wreck could happen.

Secondly, the cars should not drive themselves because they need a ton of sensors. The sensors needed in Google's modified Toyota Prius are uses position-estimating sensors on the left rear wheel, a rotating sensor on the roof, a video camera mounted near the rearview mirror, four automotive radar sensors, a GPS receiver, and an inertial motion sensor. All of these sensors and I still have not named the most important one. A dubbed LIDAR is the most important part of the technology, it is on the roof of the car and it spins. In the article it says "it uses laser beams to form a constantly updating 3-D model of the car's surroudings" but if this is blocked then it cannot sense and there could be a wreck

Overall after those 2 reasons, the last reason would be who to blame when wecking. Accidents happen all the time but in the text it says "If the technology fails and someone is injured, who is at fault--the driver or the manufacturer?" because when tecnology fails its noones fault but someone will want justice.

Score: 3
