Self-driving cars on roads with solar panels, hologram commercials, drones making deliveries, skyways between buildings, a magnetically-levitating train pulling into Circular Quay and trees. Lots more trees.

It's a view of how Sydney could look in 20 years.

A virtual reality vision of the future city has been launched as part of the four-day International Festival of Landscape Architecture in Sydney.

As well as removing the Cahill Expressway and the shops below to open up the city to the harbour, it suggests a future where cars will be replaced by a variety of futuristic vehicles - some self-driving, others that look like high-tech scooters and rickshaws.
