I was lucky enough to have dinner with Stirling Moss once, winner of the 1955 Mille Miglia and many other races. He spoke of this ability to slow down time, and how it was “automatic” and didn’t require conscious effort. He said that after his 1962 crash and brain injury… he could still drive fast but it was no-longer automatic. Instead it required tremendous concentration. He said he knew then that he must quit racing or would very likely kill himself with a momentary lapse. Edited for typo.
