Not sure if this idea originated with the Boring Company or not

Blowers make alot of sense. Instead of vacuum tubes (where people can't breath in) push cars through with wind. No air friction because you're moving with the wind, not against. Not as noisy and one can ride with the top down in a convertible. Air doesn't become stale either with a constant renewal of oxygen rich air. If fact cars could put up a sail in the back for the air to push on. Not a sail made of fabric, more like one made of sheet metal.
