It should be noted that probably the biggest reason for horrible traffic is zoning. The main reason people don't live in the city near where they work is that housing is through the roof expensive. The main reason housing is through the roof expensive is zoning and other things like rent ceilings. Making a profit by building homes in cities is one of the hardest things to do, despite that the demand for affordable housing is through the roof. The regulations are higher than the roof and it's virtually illegal for companies to build affordable housing.

The government tries to build affordable housing by ignoring the profit incentive. The irony is that affordable housing is a product of the profit incentive. If only there was some way to disabuse ourselves of the anti-scientific dogma that profits are the root of evil. More irony in that a whole bunch of atheist lefties are hook, line, sinker deep into this Biblical dogma.
