Rate the following argument fragment on its writing, argument, and language skills:
Evidence: In 2009,Google had cars that could drive independently under specific conditions. their cars have drieven more than half a million miles without crashing, but these cars aren't exactly completely driverless. For example, if you were to buy a driverless car you'd stil have to stay alert, like any other non-driverless car, but you'd be able to take your eyes off the road for about 30 seconds. If you'll have to pay attention to the car as its driving, you'd have better luck just driving it yourself. if theres an accident, traffic issues,or roadwork, you'll end up being the one who has to drive for who knows how long
