This is a very real fact in this city. Living without your own car in the city happens much more often now. With all the mass transit options, hubways, ubers, taxis, (incredibly high rents cough cough), and the option to take a zip car to the beach. It is not the hardship your old school mentality thinks it is. Truly. Not a dig.
I'm pretty sure of the 18 people in my office, at least 3 of them don't own cars. That's roughly 17% if my math is working. Which means out of 150, that would mean about 25 wouldn't own cars.
My small example works with the new units being constructed. Units who insist on having cars or even two vehicles would be forced to find off-site parking possibly, or to reconsider the need. When everything is at your doorstep, you realize your feet can get you over the threshold just fine.
This is 2016 reality, not 60's or 70's.
Btw, only about 4 or 5 of the 18 take a car to work on a regular basis, which means you a rent struggling to find parking after work if you choose to have a car. It never moved. If you travel on a weekend and can't park out front. Boo hoo, poor muffin.
