A Transport System for the 21st Century: Door-to-door automatic public Transport; Local and Trans-continental
Capital Wastage of Current Technology
The motor-car system is replete with wasted resources. At any time, over 95% of the world's cars are parked or otherwise not in service. (In Transport 21H all capsules are moving or actively waiting for passengers at all times).
Railway systems absorb an enormous amount of land.
Road-construction absorbs a ridiculous amount of capital -- redundant with Transport 21H.
