The bike is nice for singles living in cities, but let's see what folks do when they marry and need to move families with infants around.
We know what
can be done, the question remains
if it will be done.
I hope it's not just because they can't afford to operate cars but because they don't want to waste their money owning one and thus see no reason to obtain a license.
From what I've seen, the drop in licensing actually tracks pretty well with teen/twenty-something student debt and un/under-employment combined with increasing costs (purchase, fuel, insurance, etc) of auto ownership. As we used to say: Follow the money!
