text: Self-driving cars shoud not continue to be developed. These vehicles are unsafe and impractical. They require constant human attention and the liability issues are muddy, at best. For these reasons, self-driving cars should not continue to be developed, and will never become a common item in the United States.    Cars have been a necessity to us for as long as I can remember. Billions of people around the world use cars everyday. Without cars in our lives many people would be lost and not know what to do. Thinking of a world without cars is unreasonable to the people of today, but if they thought of all the good not driving everyday does for the world then it would probably be a different story.
