In Toronto the human powered divisions move an estimated 1.2 million -same day- deliveries a year within the downtown & surrounding areas. We also provide a large number of overnight deliveries in the same area. We pick-up, cache & deliver to depots items bound for other cities, filling vans that then deliver these directly to the airports to begin their journey. If you think it wouldn't be done by people in vehicles should we somehow become unavailable you'd be wrong, things have to get done. We keep 2500 cars per day off our core streets without counting the overnight & sweep services, a quantifiable difference, something people are struggling to find, quantifiable pollution & congestion relief.

In NYC, the dynamic is multiplied tenfold.

Maybe things wouldn't look much different but folks would be in their cars more, idling more, unable to find parking at all, people would be more pissed than they already are, they just wouldn't all know why prolly.
