I have watched a lot of car acceleration tests on YouTube (thanks COVID)... and the electric vehicles, especially the ones with artificial (vacuum) downforce) are approaching what seem like impossible limits. For the lesser trained drivers, the acceleration forces experienced appear to temporarily affect some basic functions (like speaking). However, these perhaps pale in comparison to the repeated acceleration and deceleration tests experienced by John Stapp - https://en.wikipedia.org/wiki/John_Stapp https://en.wikipedia.org/wiki/John_Stapp I cannot find information about his 1-second speed (trap) number, but the Wikipedia article notes that on "3 January 1955 says he accelerated to 632 mph (1,017 km/h) in five seconds and 2,800 feet (850 m), then coasted for half a second, then slowed to a stop in 1.4 seconds. It says the track was 3,500 feet (1,100 m) long."
