>I'm German. Europeans in general have tons of experience with running public transport in constrained-budget scenarios. Just ask us if you need help.

I'm sure some of us will. That said, Europe is only directly comparable to the Northeast in terms of geography, climate, and population density. The US is truly massive, and each part of the country has distinct cultural norms which may or may not support public transit development.

According to this page (https://nytransit.org/resources/public-transit-facts), ~60% of people on public transit are commuters. Here's a 2021 study from our Census Bureau on commuters using public transit in the US (https://www.census.gov/newsroom/press-releases/2021/public-t...). The key points:

>About 5% of all U.S. workers in 2019 commuted by public transportation.

>Commuters use buses (46.3% of all public transportation commuters, or about 3.6 million people); subway or elevated rail (37.7%), long-distance train or commuter rail (11.8%); light rail, streetcar or trolley (3.1%); and ferryboat (1.0%).

>Roughly 3 million of the nation’s 7.8 million public transportation commuters lived in the New York metro area.

>70% of the nation’s public transportation commuters live in one of the seven largest metropolitan areas.

>The percentage of workers who commuted by public transportation varied by region. The Northeast had the highest share of workers who commuted by transit, at 14.3%, followed by the West (4.4%), the Midwest (3.0%), and the South (2.0%).

>The percentage of U.S. workers commuting by public transportation fell from 12.1% in 1960 to around 5.0% in 2019.

The most surprising statistic to me is that NYC accounts for roughly 40% of public transportation commuters in the country. The rest make general sense.

>The goal is to get the remaining 99% of local/regional individual-transportation traffic to use shared services.

Well, that is YOUR goal. The vast majority of Americans do not live in dense urban environments, so most will not support your goal. That's okay; we have our own mixture of geographic, climate, and population density realities which differ from your own. (Actually, you would be better served talking about measures in different states rather than the US as a whole, because we're built state-first, not federal-first like all European countries save for Switzerland.)

You might find it interesting that, in some parts of US suburbia, individuals and families roam around towns riding electric golf carts instead of cars using separate roadway infrastructure.

As an American who (1) generally supports mass transit and non-personal-car modes of transportation while (2) understanding the globally-unique geographic, climate, population density, and cultural realities of the US, here's how I envision mass transit will look in a few decades across the US:

>Planes: widely used everywhere, airports are linked to urban centers by rail or BRT

>Trains: same cross-country lines exist, Northeast network continues strong, train networks in Florida and on the Pacific Coast expand, lightly used for regular transit in 80% of states

>Light-rail/subway: most major US cities have one, existing networks see varying degrees of expansion, ridership increases handled by more frequent trains

>Trams: used in dense urban cores of major US cities which do not have extensive light-rail/subway network, sees strong ridership, trackless more prevalent than track

>Streetcars: limited use, electric trams or buses more preferred due to track and electrification infrastructure and maintenance costs

>BRT: widely deployed across major urban areas, used to either extend light-rail/subway reach or provide hub-to-destination travel

>Buses: still widely used, expanded service in both urban and suburban areas, direct home-to-station travel facilitated by autonomous microbuses

>Bike infrastructure: widely deployed across all major urban areas and most suburban areas, virtually all old railroads converted to bikeways, some new bikeway construction for commuters, protected bike lanes in all dense urban cores

>Cars: still used each and every day by the majority of Americans, many are electric, some are autonomous
