A kind of little car may someday take the place of today's big ones. If people drive such cars in the future, there will be less pollution in the air. There will be more space for parking in cities. The streets will be less crowded. And driving will be safer as these little cars can go only 65 km per hour. The future cars will be fine for getting round a city, but they will not be useful for long trips. Little cars will go 200km, before needing to stop for more gas. If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be used for the big fast cars and other roads will be needed for the slow and small ones. It's said that three such little cars fit in the space now needed for one car the usual size.

　　一种小型汽车某一天可能会取代今天的大型汽车。如果将来人们开这样的车，空气中的污染会更少，城市会有更多的地方停车，街道也会不那么拥挤。驾驶也会变得更安全，因为这些小车每小时只能行驶65公里。未来汽车会适合绕城行驶，但是不适合长途行驶。小汽车在需要加油前能够行驶200公里。如果大车和小车同时使用的话，将来将需要两种道路。一些道路是快车专用，其他的则给慢车和小车专用。有人说，三个这样的小车才需要一辆现在一般汽车大小的空间。
