Rate the following essay on its writing, argument, and language skills:
I am for the development of smart/driverless cars. I have chosen to support these cars because they will use half the fuel of today's taxis and offer more flexibility than a bus, they can sense the road and dangers better, and the cars require little human attention.

Firstly, the cars will potentially replace taxi services. I think this will be a great idea because while you would still have to pay for the service, there is no human element of error. If there is an element of error, however, you will be the one at fault because you are the only passenger and driver. I believe the replacement of the traditional taxi service is a good thing.

The smart cars are good at sensing dangers on the road ahead. Because the cars have technology that can even start to turn on the brakes before the driver can, the driver will be safer and does not have to respond as quickly. The "Traffic Jam Assistant" is a good development because the driver must still remain alert but the car does most of the work.

Lastly, I think the smart cars are a good idea to develop because they allow the driver to be safe in a vehicle that they are not in full control of. A project manager driver from BMW, Werner Huber states, "We have to interpret the driving in a fun new way." I think that if the developers of the smart car add a type of entertainment to help the passenger stay interested, then the driver will still be alert.

I believe the development of the smart car is a good idea because people will not have to take a taxi anymore, the smart cars are more reliable, and the smart cars will require less attention from the driver. I believe that the smart cars will do a good job on the road and that there are very few risks if they are tested correctly.
