The average reaction speed of a human to unanticipated situations can be ~3 seconds. Any connection within 1000KMs is generally going to be under 0.1s - an orde

  I'll take your word for that, but remain unconvinced. I don't think it's just about reaction time. Playing a game with input lag is terrible because you always need need to do all your inputs ahead of time in anticipation what a frame 100ms in the future will tell you. That might make precise control very difficult, not just in unanticipated situations such as e.g. emergency braking.

    Games generally already involve adrenaline and focus, where you're primed for action to happen. Unexpected road accidents typically involve someone who may not even be thinking about driving, who then have to notice the random screech, focus their eyes and process what's happening, then determine they need to immediately break, then break. The problem with input lag isn't that human input is under 100ms, it's that too much of a gulf between input and on-screen response breaks the feedback loop - your brain struggles to connect your input alterations to an alteration actually happening. If you're throwing a ball, when you twist your wrist the ball is twisted immediately when the wrist holding it is twisted (because it's physically pinned to the hand that's physically attached to the wrist, and literally cannot be out of sync with the fingers gripping it). It's like how VR users need under 30ms of latency or they throw up, except less drastic.
