Rate the following argument fragment on its writing, argument, and language skills:
Evidence: Cars are one of the main sources for people's stress, whether it be because of car failures, others who annoy you while you drive, or the fact you can never find a parking spot.  Heidrun Walter claims " When I had a car I was always tense. I'm much mappier this way ( In German suburb, Life goes on without Cars 3)." One main reason people are less tense and stress is because people do not have to constantly worry about if another car is about to hit them, if traffic is going to be to slow to get to work, or if your car is going to breakdown on you. Car's create unwanted stress that can be easily avoided. Indeed life would be very different without cars people in Bogota, Paris, and Germany have all been able to function properly without motorized vehicles.  In fact "70 percdent of Vauban's families do not own cars, and 57 percent sold cars to move her (In German Suburbs, Life goes on without Cars 3)." These individuals have proven that it is okay to make a switch.
