Nothing I'm saying is actually scientifically controversial. I'm literally citing facts from urbanist textbooks. It's just that the way I'm telling them is unsettling for the people who have never questioned the social-engineered "consensus".
The CO2 footprint question is a tricky one. The vehicle _itself_ is not the main source of pollution. Even if you compare the vehicles, the answer is not straightforward: https://ourworldindata.org/travel-carbon-footprint The main source of pollution for transit are _drivers_. E.g. each bus needs around 3 drivers to function, resulting in driver-to-passenger ratio of just around 1:7.
So when computing true CO2 footprint, you need to look at a counter-factual scenario where bus drivers are doing something else. But this becomes extremely tricky extremely fast, as you can move into fantasyland where bus drivers are building CO2 scrubbers instead of driving CO2-emitting vehicles. Or where drivers are working on chopping forests for agricultural lands, resulting in huge CO2 increases.
The next best option is to look at different regions and compare them. E.g. Houston, TX with EVs would have smaller CO2 emissions than the current NYC, with climate corrections.
The article you cited doesn't support that assertion. Its thesis is that upzoning alone — i.e. relaxing regulations such that it is legal to build higher-density housing, without further interventions — may not be sufficient to create enough vacancies to lower rents.
The cited article alone simply admits that upzoning won't result in cheaper housing. Because the market is broken (and only socialized housing can fix it), but we must do upzoning anyway.
That article also doesn't support your assertion. For example, they specifically call out parking minimums and minimum lot sizes (both density-lowering regulations) as major drivers of high housing costs.
E.g. density doesn't decrease housing prices: https://www.strongtowns.org/journal/2023/4/26/upzoning-might...
