F1 cars are so fast that they need 100% concentration at all times. The yips sounds to me as a phrase I would use if somehow the reality of the risk and absurdity kicks in.

If not in flow, your actions aren’t natural anymore, instinct is gone, in other words, an off day. Flow is also our main source of happiness.
