🏎️ 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?
| 👁️ | Focus | Sustained attention to the lights is crucial. |
| ⏱️ | Anticipation | Your brain predicts timing — but the delay is random. |
| 😴 | Sleep | Fatigue slows reaction by 30–80ms. |
| ☕ | Caffeine | Can improve reaction by 5–15ms. |
