What’s a big problem in Shenzhen today, do you think? Besides pollution, traffic is, of course.

There are too many people, too many cars but too little space so the roads are always busy. You can almost see traffic jams everywhere. It is even worse when everyone is going to school or to work. What’s more, cars need fuel(燃料) to move, so they let out a lot of dirty smoke and pollute the air.

It is said every car will have a computer. The computer can study the latest traffic news. Then it will look over its own map for the best way to drive and they won’t get into traffic jams.
