self­driving cars with reclining seats (可躺座椅). People may choose to live farther outside of cities if they can travel in cars that allow them to sleep and relax. But that increases the number of people travelling in and out of cities during rush hour, Fulton said.

　　Without the cost of a driver, Fulton said he worries self­driving Ubers or Lyfts will become so cheap it will be hard to push people to choose car­sharing services like uberPOOL. "I think it's going to take some kind of pricing system that discourages cars without a single passenger，" he said.

　　Some cities have already started programmes that discourage people from taking car trips alone. For example, Chicago and New York City have set up lanes (车道) that single­passenger cars must pay some money to use. That money increases during rush hour.
