SINGAPORE - Cars may one day go out of fashion in Singapore, said National Development Minister Khaw Boon Wan, as he envisions a city with fewer vehicles and more space for living.

"It is already happening in some European cities," said Mr Khaw in a blog post on Tuesday. "Youngsters no longer see a need to take driving lessons, let alone buying a car. People are walking, cycling, taking public transport. The occasional car needs can be satisfied more cool-ly, via Uber or Zipcar or many such local ridesharing equivalents."

Noting that carparks might eventually become "excessive and redundant" as a result, Mr Khaw urged the public to participate in Singapore's second annual Park(ing) Day on Friday.

Supported by the Urban Redevelopment Authority, the event allows the public to temporarily transform carpark spaces around the island into anything from parks to living rooms. So far, there have been about 50 registrations from community groups, local businesses and student bodies, said Mr Khaw.

He said: "The mission is to get everyone to envision a city with fewer cars, and more space for people, for living."
