I've been watching NotJustBikes[1] on Youtube recently and he really drives the point home of how screwed up infrastructure is in the US and Canada. The problem for us seems to be cultural, we consider public transit to be a form a welfare rather than actual public infrastructure. We consider taking the train of the bus a thing you do if you're to poor to own a car and anytime expansion of a subway system is considered, there's always the kneejerk reaction of "you will bring crime to the suburbs".

And anytime we do build a mixed use development, we make sure that it's marked as "trendy" and "hip", as to not give the impression that this should be a normal mode of development. Anytime a development like this goes up, property prices around the development are out of reach to working class families and that even further drives the point home that this is not a normal mode of development, rather a playground for the wealthy (and you're going to need a car to get there if you don't live in the million dollar townhomes around the corner).

When these mixed use developments do go up, American's are amazed by the walkability and livability. News outlets do puff pieces on these new developments and everyone is happy about it, then when it's time to do more development around the city we go back to the old ways of segregating everything to the nth degree.
