Volvo diesel cars avoid turbo lag by storing compressed air. Not very relevant but interesting nevertheless https://www.roadandtrack.com/new-cars/car-technolog

  And Bosch uses compressed air to keep motorcycles on track (experimental tech) https://www.youtube.com/watch?v=3ERowrZJyfw https://www.youtube.com/watch?v=3ERowrZJyfw

    If you could point them backwards for a little extra thrust ...

      Modern supersports are pushing ~200hp, no need for the extra weight that would generate the thrust.

        The Spitfire actually used the jet propulsion of the rearward facing exhaust for an extra few horsepower. Many piston engine aircraft do this.

  ABS braking does the opposite: a vacuum is stored that's used to release the brakes in short bursts.

    Modern (post 1990-something) ABS has its own pump. Air brakes on trucks run in reverse. Compressed air releases spring pressure therefore releasing the brake.

      > Air brakes on trucks run in reverse. Compressed air releases spring pressure therefore releasing the brake. I think pneumatic brakes almost universally work this way, because it's fail-safe w.r.t. line leaks. E.g. in trains the main air line is for powering pneumatics as well as releasing brakes; at nominal pressure (8-10 bar iirc) the brakes are released, at lowered pressure (3-5 bar) the brakes are fully applied. If the line ruptures or the train splits all brakes across the train are fully applied.
