Part 1: It has been confirmed by @ValtteriBottas with regard to what happened to his start at the #HungarianGP #F1;
"I believe it was the main page of the dash changed a different colour or something - a really bright colour." https://twitter.com/AnnotatedWA/status/1284925823867215872">https://twitter.com/Annotated...

Part 2: @ValtteriBottas has his Dashboard& #39;s Launch RPM helper background colour set-up to the following;
https://abs.twimg.com/emoji/v2/... draggable="false" alt="⬛" title="Schwarzes großes Quadrat" aria-label="Emoji: Schwarzes großes Quadrat">IDLE - Clutch Engaged, 0% Throttle
https://abs.twimg.com/emoji/v2/... draggable="false" alt="⬛" title="Schwarzes großes Quadrat" aria-label="Emoji: Schwarzes großes Quadrat">TOO LOW - Below optimal revs
https://abs.twimg.com/emoji/v2/... draggable="false" alt="🟥" title="Rotes Quadrat" aria-label="Emoji: Rotes Quadrat">RPM GOOD - At optimal revs
https://abs.twimg.com/emoji/v2/... draggable="false" alt="🟪" title="Violettes Quadrat" aria-label="Emoji: Violettes Quadrat">RPM HIGH - Over optimal revs

Part 3: What Bottas reacted to & released his clutch was when his revs momentarily went to https://abs.twimg.com/emoji/v2/... draggable="false" alt="🟪" title="Violettes Quadrat" aria-label="Emoji: Violettes Quadrat">RPM HIGH

You might ask, "but the Red LEDs indicating optimal revs went off first"
- This is caused by a fault of the new T-cam @F1 are trialling, which does a bad job at processing LEDs

Part 4: With the handicap of not being able to observe the start revlights, I could only rely on his Dashboard& #39;s screen and text/colour RPM helper, in Part 2 of this thread.

You can observe a clearer view of the Dashboard Launch RPM helper in the 3rd part of my video analysis

Part 5: I hope that this video would be a great help to uncover the mystery for @MercedesAMGF1 @ValtteriBottas and for Sky F1& #39;s @antdavidson @karunchandhok
