🏎️ F1 Start Context

In real F1, drivers react to lights-out in 100–300ms. The five-light sequence builds anticipation and tests your ability to react to the absence of a stimulus rather than its appearance — a harder cognitive task.

A false start (jumping the lights) incurs a penalty, just like in a real race.

⚙️ What Affects It?
👁️FocusSustained attention to the lights is crucial.
⏱️AnticipationYour brain predicts timing — but the delay is random.
😴SleepFatigue slows reaction by 30–80ms.
CaffeineCan improve reaction by 5–15ms.
