I support computer and HSR even though irs a waste here and let me explain
Population density, the USA only has the density for high speed rail to make sense among the northern Atlantic coast
Everywhere else is rural to semi rural, even our major cities out west you could bring a train into the city center but the cities themselves are largely suburban in character with little in the way of local train networks to make the network really useful and convenient like seen in Europe or Japan.
Even Manhattan, by far the densest place in North America and one of the densest areas on earth 20% of daily commuters (1/5) drive in a single occupancy car from home outside the island
Trains will not make sense for travel in America for a very long time, if you real want trains support the buildout and improvement of local and regional mass transportation systems, then down the line you link these sequestered local and regional rail/bus/tram networks via dedicated direct high speed rail routes
