F1 Reaction Test
The real Formula 1 start procedure: five red lights come on, then tap the instant they all go out. Tap early and it's a jump start. Real F1 drivers react in roughly 0.2 seconds.
The F1 lights measure how well you wait for the moment they go out. MIKIRI measures how fast you read something the instant it appears. After waiting comes reading.
Can you read a number that vanishes in 0.4s?Bonus: can you read a number shown for 0.4 seconds?

How a real F1 start works
At a Formula 1 start, five red lights illuminate one at a time. The signal to go is the moment all of them go out. The gap between all-on and lights-out is deliberately randomized by the race director at every real start โ and in this test too.
React before lights-out and it's a jump start โ a penalty in the real thing, a retry here.
How fast are real F1 drivers?
Measured driver reactions at the start are commonly cited at roughly 0.2 seconds (200ms range). Given the human visual floor of about 150ms, that's about as sharp as it gets. If your 5-run average beats 260ms, you have genuine pace.

FAQ
- How many lights are there at an F1 start?
- Five. They come on one at a time, and the start signal is the moment they all go out.
- How fast do F1 drivers react?
- Commonly cited figures are in the 0.2-second (200ms) range. The human visual reaction floor is around 150ms.
- Is the lights-out delay random?
- Yes โ in real F1 the race director varies the delay every start, and this test randomizes it the same way.
- Is it free?
- Completely free, no signup. Works in any phone or desktop browser.
