Rate the following argument fragment on its writing, argument, and language skills:
Concluding Statement: The system works, and it works well, so why change it? Driverless cars may sound high-end and futurisitc, but our cars now do the job well. Plus, there are hazads and roadblocks the driverless cars will have to overcome first. Should we really make state legislatures waste time debating the use of a driverless car that is not completely driverless? Driverless cars have benefits, but they are not street legal. I see no point in spending money for a car that cannot be driven in most streets and is not able to operate without a human there to takeover incase something goes wrong.

Score: 2
