  • There are also far fewer of them per passenger, so fewer chances for one to come by. They are also operated by professionals who can call in sick if their ability to operate the vehicle is impaired.

    A bus could be ten times deadlier in a crash than a car and it would still be safer if it carries fifteen passengers. It could be a thousand times deadlier if operated by a drunk person and still be safer than cars because drunk people don’t operate the vehicle when getting home by bus.

    Car crumple zones are tuned to prevent damage to the car, not to pedestrians. If they were they would have airbags on the front of the car. A car can kill a pedestrian by hitting them with a crumple zone, without that zone crumpling.

    This means most of the non-elasticity is in the pedestrian’s body; how they flop onto the hood of a normal car, and how their bones crumple and flesh splatters before their brain and vital organs do.

    Of course if a car hits a pedestrian hard enough, the crumple zone will crumple to reduce damage to the car, but that’s overkill as far as the pedestrian’s life is concerned.

    That said, if you (unrealistically) assume the speed at impact and the geometry of the hood are the same, the difference between a car that weighs 20 times what a person does and one that weighs 40 times that is (40/41 - 20/21), or only about 2.5%.

    Realistically, the weight increases the braking distance and the hood geometry makes the pedestrian’s body perish more elastically.




  • tl;dr: The “zero knowledge” proof could have a finite number of uses per block of time for each verifier, each of which represented by a unique single-use key. This way anyone sharing keys would be limited by that finite number of uses, and if people sharing this aren’t coordinated they could end up re-using a single-use key.

    If the encryption was stolen without their consent, this could tip a user off prompting them to invalidate the current set and get a new one. And if the verification is used to support a pseudonym like an account for an online service then instances of re-use could get flagged for moderators.





  • The issue is that it’s not one problem, it’s thousands. Anarchism has countless solutions for countless power vacuums, from regulating the flow of meetings to federating different Zapatista towns.

    You yourself are probably engaging in anarchic power vacuum mitigation when your friend group decides when to hang out and what to do; if anyone got too much power or responsibility you would take action to make things fair again.

    Generally speaking, power vacuums are dismantled by dissolving the hierarchies that can be dissolved, changing the material conditions so power is decentralized, and building a social structure to hold the remaining power conditional on not being authoritarian. You can probably remember doing these things with your friends (or former friends).

    Anarchist theory is either descriptive, like critically analysing the Zapatistas, or it’s putative, like sociocracy. So far we have no proven overarching theory of what works for everyone everywhere in every situation, but we do have lots of small anarchist collectives that are benefiting their members and their society in limited scopes.
