    The 85th percentile rule is why Civil Engineers catch shit about not being real engineers. It’s basically:

    “How fast can cars safely go on this road?”

    “I dunno. How fast are they going now?”

    Speed limit should be factored into (and a function of) road design, not just measured and guessed at after the fact.
