Rate the following argument fragment on its writing, argument, and language skills:
Evidence: The fact that these vehicles are semi-autonomous and not completely autonomous enables a human driver to take control whenever they deem it necessary to do so. For example, Google's semi-autonomous creations are "not truly driverless; they still alert the driver to take over when pulling in and out of driveways and when other complicated traffic issues arise."

Sensors are what enable these vehicles to perform the tasks that astonish many to this day. Due to the fact that sensors have been used since the 1980s, vast improvements and tests have been conducted over the years to ensure that the safety of the consumer and those around he/she are preserved. The article even states that "Within 10 years, those sensors [from the 1980s] had become more advanced to detect and respond to the danger of out-of-control skids or rollovers." These vehicles allow for the potential decrease in drunk driving, which further emphasizes that safety is not only preserved with semi-autonomous cars, but is heavily increased.
