Hyperloops use magnets to levitate pods inside an airless tube, creating conditions in which the pods can shuttle people and freight at speeds of up to 750 miles (1,200 km) per hour.

They do? Where are all of these functioning prototypes?
How do passengers get in and out of a pressurized pod quickly in a vacuum tube? How do passing sidings, junctions, etc., all work? How is a near-vacuum maintained over a vast distance when a tube must have hundreds of expansion joints?
Basic questions haven't been answered and you're the bad guy if you raise them.
