I worked at Papyrus (maker of Indycar and NASCAR games in the mid-late 90s and several alumni founded iRacing).

I’d introduced arcade mode and double-tap-hold to do a burnout (intended to make tight pit-out and 180° turns after wreck easier) to the Playstation version.

Inadvertently, I neglected to reduce forward traction during the burnout, so a burnout was the fastest way to do a standing start (by virtue of getting into the higher power RPM band). Made for interesting standing start races. Burnout made it into our “Hawaii” multiplayer code and NASCAR2 code; I don’t remember if Arcade mode (looser but more catchable cars and much better brakes) did or not.
