Rate the following argument fragment on its writing, argument, and language skills:
Evidence: Global warming is a problem that needs to be dealt with and one of the major culprits of it is the exhaust from diesel burning cars. The cars that Google is manufacturing are attempting to use half the fuel of a regular car while providing a safer function. With computers that can regulate exhaust, it is not too hard to imagine in the near future, if given more research, that a self-driving car could accomplish such a feat. Driverless cars would also be more efficient in that they would cut down on transportation time between destinations. Using GPS features, an autonomous car could calculate the quickest route to a destination and it would never miss a turn. Self-driving cars would not only be more fuel-efficient and help save the environment, but they also would be more time efficient.
