point taken, the "p value" way of talking is confusing when talking to people doing real work and not reading articles, you're right (I was with my mind deep in reading some medical research articles actually so my mind "stuck" on this wording...) but it's just about: probability of scooter A and B failing at the same time is their probabilities of failure multiplied and for a "swarm" the probability of everything failing at the same time decreases exponentially with the swarm size - eg. the probability of 10 scooters with a 50% each probability of failure failing at the same time is less than 0.01% ...thinking probabilities is what you end up doing even if you do smth like devops and try to do a good job at it when stretching resources thin :)
