Rate the following argument fragment on its writing, argument, and language skills:
Evidence: Driverless cars can allow people to safely engage in other activities besides driving, allowing them to achieve and accomplish more. Driving can be tiring, and driverless cars eliminate driving as a task for people to complete. Many factors can impair driving ability and prevent one from driving, but with driverless cars, mobility is always possible, and transportation is always accessible. A Google cofounder estimates that driverless cars can eventually eliminate the need for personal cars at all, by introducing a public transportation system of entirely driverless vehicles, and that these vehicles can use half the fuel of current taxis. This can have huge benefits for the environment.
