Rate the following essay on its writing, argument, and language skills:
In my personal opinion driverless cars are not the best idea scientists have ever discovered. I feel like driverless cars would be a very dangerous way for people to get from place to place. I also feel like there would be more bad aspects then good on this subject. On the other hand, they would be very useful and convenient.

In my opinion I think that driveless cars could be a very dangerous invention if they were not tested enough in varius ways. For example, what if there was a situation were someone was driving down that road and their car misfunctions or something electronically happens within the engine. Not only would the driver be in danger, but all the other cars around the smart car could be too. In paragraph four, the option of smart roads was discussed. I think it would be safer to try inventing roads that help the car before inventing a car and expecting it to do all the work by itself.

The bad things by far outweigh the good things when that idea of smart cars get brought up. Smart cars need a lot of electronical materials to not need a driver anymore. That is a huge risk anyone would be taking when stepping foot into a smart car. At any moment in time the electronical systems could crash or if the smart car was to need internet and something happens to the web. Another aspect of this discussion would be the law. If you, being the driver of a smart car, got into an accident and it was not your fault, you are not going to want to pay for the damage. Many laws would have to be changed in order for ordinary people to be able to drive smart cars on the roads. It a huge discussion of weighing the bad things and good things with the subject of smart cars.

On the other hand, smart cars would be very convient. In paragraph two they discuss that in today's day in age we have all the technology to allow smart cars to be manufactored. All different types of products are being manufactored with new technology everyday. Why not manufactor a smart car? Buying a smart car would be great for older people that can not get out and drive by themselves, but it still wouldn't help very much. This is my reasoning on that, the elderly person still might have to drive a little bit if something was to happpen and they run into a construction site or accidents. It may even be more dangerous for the older person to have to switch back and forth from the car being driven for them to them having to operate the vehicle.

Again, in my opinion I think smart cars are a bad invention unless scientists were to invent road systems that matched up specificely to a car. There is to many risks to be taking at this point in time in the progression of smart cars. Possibily in the future when scientists discover more about them they might be better and more reliable.
