Trucks, cars, & planes have great logistical advantages overas it stands now, everyone is already paying for roads, rails, airports and seaports, and all the vehicles that use them. Some are more subsidized than others, but the costs are included in the price of, well, everything.
If governments from the local to the national hadn't spent the last 80 years underwriting automobiles and the trucking industry, as well as the aviation industry, then we'd likely have a reasonable passenger train system and mass transit systems in the US
"Individual choice" for the freedom of the automobile was heavily subsidized and the competitors eliminated, forcing everyone but the very poor to play along. For the urban poor, mostly ineffective mass transit has been underwritten as an afterthought.
trains. Trucks & cars are door to door without intermediate
transfers to other delivery systems. Planes are fast, & have
cost-free routes.
(Although rail freight has bulk hauling cost & energy advantages
when serving dedicated facilities.)
But maglev....it suffers from big disadvantages....
- Expense & difficulty of getting new rights of way.
- High construction cost.
- The route is a single line, which means trouble for intermediate
stops....they must either slow things down, or be eliminated.
This is a problem with passenger rail too, & explains its downfall.
Do the poor need maglev service between major cities?
Nah. They need practical commuting solutions.
