"In a quality city, a person should be able to live their entire life without a car, and not feel deprived."
As Bedford points out, the opposite is also true:
"A good sustainability and quality of life indicator: the average amount of time spent in a car."
(Elevated time car-commuting time also turns out to be a reliable metric of social isolation and general life dissatisfaction.)
With Internet, society should be able to deprecate the "city". We don't all need to be stacked on top of each other, in homes, in cars, in subways and so on.
Doubt I will see it in my life time...
