Given that it takes a long time to bring a street up to standard (budgeting, design, contracting, and constructing), that would probably be 10-20 years at an optimistic estimate to get every street up. In that time, under your proposal, the roads would become undrivable, and therefore:
Emergency vehicles would be unable to operate. Thousands die.
Traffic increases exponentially as the usable roads become increasingly infrequent and commuters flock to the few good ones. The above problem is made worse; gas usage increases dramatically as more and more cars sit idle for hours a day.
Highway safety plummets. Thousands die in avoidable crashes.
Roads become impassible to trucks. Deliveries of food and goods grind to a halt. Starvation, food riots, economic collapse follow.
I’m all for increasing walkability and bikability; I’m fortunate enough to live in a city that is both, and it’s great. Proposals like this, however, do nothing but make it look like the movement is a bunch of “fuck cars” knee-jerkers who know nothing about infrastructure and can thus be safely disregarded.
