text: A decent amount of stress comes with owning and operating a motorized vehicle.  You are constantly worrying about if you will be late, or if you have enough gas to make it from point A to point B.  Children are another concern and trying to keep them safe around roads and driving by themselves.  Limiting the use of cars can create a less stressful, and safer society.  In Source 3 it explains that, "Parks and sports centers also have bloomed throughout the city; uneven, pitted sidewalks have been replaced by broad, smooth sidewalks; rush-hour restrictions have dramatically cut traffic; and new restaurants and upscale shopping districts have cropped up."  Lowering the use of cars can make life a little less busy because it is one thing less that you have to worry about throughout your day.  Heidrun Walter said, in Source 1, "When I had a car I was always tense. I'm much happier this way."  Reducing the usage of cars can promote a less stressful and safer lifestyle here in the United States.
