These same people are ostensibly liberal, "we're all for people riding bikes, or getting a stupid little condo, whatever you kids like to do for fun" they say, but in practice will do anything in their power to prevent any impediment to their car commute, even if their fear is at-best specious.
Same thing in Toronto. In Vancouver Canada we're a fair bit better about the bike lane thing, though it's still fragile, but in the affordable housing issue they actually just subsidized the huge home owners that already owned land, so a majority of new units that have come on the market are in their basements or backyard and can't be owned, furthering a class divide. They marginally upzoned, but now a duplex or small townhouse is over a million at the low end. There isn't an incentive to make housing less expensive except the vague sense that the municipal/regional economy will eventually collapse on someone else's watch.
