maybe because it was to easy to upload to the googleplay store. Maybe there should be some kind of verification of the person uploading. How could this be accomplished?

Joking aside I don’t think side loading should be encoumbered like this, but for the official app store it makes sense.

hyperloop was very low air pressure subway tubes for high speed trains. Works for research tesring tracks impractical to infeasible for real world applications. But it apparently what killed high speed rail in california (because wait this will be better)

The cars in tubes thing was a seperate stupid idea.
