Recent headlines point to the seismic modal shift underway in Seattle transportation. Bike and car sharing, electric vehicles, expanded light rail and driverless cars are opening a world of choices to Seattle residents who used to be solely reliant on their own automobiles.

The average US city devotes between 30% and 40% of its surface area to roads and parking, compared to less than 5% for parks.

What are the inherent opportunities this shift opens for the design of our cities? How might we want and need to reimagine our urban fabric? Should we create a vision now for what our post-car city should look like?
