Rate the following argument fragment on its writing, argument, and language skills:
Evidence: The driverless cars that Google cofounder Sergey Brin foresees would use half the fuel we use today. Fossil fuels are becoming an issue, but what if we had one less use for them? Without the need for so much fuel that wouldn't be so much of an issue anymore, and we would have more time to plan for whenever the time may be that we run out of fossil fuels. Also, if we perfected the driverless car there will be a lot less crashes. Without so many crashes we wouldn't be paying for repairs as often. We also wouldn't pay for the medical bills and such associated with an automobile accident.

Score: 2
