Rate the following essay on its writing, argument, and language skills:
In todays society new inventions are constantly being produced. For example, driverless cars, a new model of car that no longer requires as much hands on driving. Some may agree that what the world needs are driverless cars, but in my opinion driverless cars aren't the safest technology to rely on for our transportation. Driverless cars can either benefit or negatively impact our world today.

To begin, I worry that people will not take safety as serious as they currently do. If we have a car that drives itself, people may get too comfortable with not having to be alert on the roads. Studies have shown that driverless cars still need human assistance when, "naviagting through work zones and around accidents" (paragraph 7, line 7). If a driver is too busy on their phone because the car is doing all the driving, then they may miss what's ahead of them which can put them at risk of causing a wreck. In these situations legal standards may become a problem. If the car wrecks, "who is at fault- the driver or the manufacturer?" (paragraph 9, line 12).

Drivers may become less aware of the fact that technology sometimes fails and you will always need to stay alert.

Furthermore, how smart will these cars really be. For example, how will they know when the speed limit changes? If the speed limit is 40 and suddenly you are in a school-zone then it changes to 25, there is no way the car is able to read the street signs. The passage states that, "they can steer, accelerate, and brake themselves" (paragraph 7, line 5), informing me that the cars are smart enough but only in certain situations. This could cause major problems with traffic cops and wheather they should give you the speeding ticket or the car. Looking back on the legal issues, "who is at fault", (paragraph 9, line 12).

In conclusion, there is always room for improvement when it comes to driverless cars. New technology still needs to be produced in order to get these cars working right. We need to keep in mind if these cars are safe enough to rely on. New technology isn't always the best option, driverless cars may impact our lives in ways we never thought they would.
