And the National Highways Act helped doomed public transportation.
Today we get to sit in congestion because Highways aren't properly maintained. Subsidized Highways and broke cities and suburbs. That's why we're the only society in the world that is built around cars. Cities were designed around people. The suburbs are designed around the car. Suburbs don't have the population density to support public transportation. So hence it's a choice to live in congestion.
Not really. Congestion and jams occur, because of the lack of coordination, high reaction times, and low attention spans, and scofflaws.
You could keep adding lanes to any given road--and congestion won't decrease. Because as more lanes are added more people will take the main line route. It is something highway/road planners have come to terms with thanks to computer modeling
