A driverless streetscape? Plan on it

Streets will be transformed in the coming years, with driverless car technology and other changes. (Dreamstime)

To find a prism into how cities and suburbs will evolve in coming years and decades, look no further than the lowly curb. 

That concrete barrier between street and sidewalk has always been that place where we park cars, alight buses and hail taxis. During parades, it's that makeshift bench that gives our tired legs a moment of rest.
