The widely use of private cars is a reasonable outcome of modern industrial development. It generally makes our life convenient. However, the side effects are emerging from the rosy surface.

Most importantly, I do hold the opinion that the use of cars should be limited by law including private ones and public ones. Only by doing so can we reduce the risks mentioned above before they become realities.
