Visitors to the 2010 World Expo in Shanghai will be able to go sightseeing in super cool cars with no drivers，Shanghai city officials said recently．

When a prototype(原型)of the six-seats car was shown to the public，it interested many people．“The car will help visitors feel what high technology is and help them enjoy a tour of the World Expo site，” said a professor at Tongji University．He was in charge of the project．The prototype ---4.5 meters long，1.7 meters wide and 1.6 meters tall runs along a white line．The cars costs around 300，000 yuan to build and can reach a top speed of 50 kilometers an hour．

According to the researchers，visitors will be able to drive the car anywhere in the World Expo site by pressing a button．If they want to get off or stop the car，all they need to do is just to press the button again．

“People can rent one of these cars for a whole day or just take a ride in it from one place to another，”the professor said．Around 400 to 500 of these cars will be made for the Expo in 2010．The cars will have radar(雷达)to help them get around people and buildings．They will mainly use solar batteries(太阳电池)and lithium batteries(锂电池)．As they have no needs for drivers and oil，these cars will help save energy and human labor and cause no pollution to the environment！
