Coefficient Giving's @mattsclancy reveals why America's biggest transportation breakthrough might not be high-speed rail, but cutting massive infrastructure costs: "If we go big on transportation, it’s not a given that it will look like we should all have high-speed rail across the country. It might be more about autonomous vehicles. It might be about congestion pricing." "Probably a big part of it will be about why does it cost so much more to build the same kind of transit infrastructure in the United States than in other countries." "We’re thinking what are the impacts on the ability of people to access the agglomeration benefits of a city cluster, what are the impacts on carbon and climate, what are the impacts on life expectancy, if you think autonomous vehicles are safer than human-operated vehicles." @coeff_giving
