Barcelona is hot too but somehow it works, bc less cars and more trees(especially near sidewalks) means nicer walking even in hot summer "Greater Houston is 10,000 square miles with 7.5 million people. Greater Amsterdam is 1000 square miles with 2.5 million people." - yes, we know that american towns are inferior because of parking requirements and local zoning, yes the problem is more complex, but does this mean it's not a problem or ppl just should start slowly fixing it? (Like abolishing parking reqs, zoning laws and just pass a law that forces companies to build a nice sidewalk&bike lane when a street is renovated, slowly fixing the problem). We can't know for sure walkable city will not work in Huston because laws generally prohibit building one with those stupid requirements
