Rate the following argument fragment on its writing, argument, and language skills:
Evidence: It's more convenient to just hitch a ride from someone such as a friend or a taxi. But sometimes those aren't always the most convenient options. Taxi drivers could take someone anywhere or your friend could be under the influence. Driverless cars are safer because they could take you where you need to go safely. They are also more convenient because sometimes people could be impaired and unable drive, so they would just have a driverless car pick them up instead. This way, it is convenient for people to travel without worrying if they are going to be safe or not.
