I had a ‘dream’.
During my childhood, I can’t go outside to play with other kids because they are many cars on the rode with driver who do not obey the traffic rules. Each time when I was looking at the road and cars. I was thinking , if one day there are no more car on the road, how would the world look like? No more cars, the only traffic tools which people have is their legs. Children can play anywhere they want, everyone can get the exercise of the body because they can’t drive ,take bus or subway. No more air pollution and noise.
