I keep thinking about this and now your comment reminded me of it: did OpenAI have a "gym" 10(+?) years ago where autonomous cars were trying to navigate Los Santos in GTA5? If not, whose work was it and why did it come to an end?

Wasn't this gym thing a big task where some guy was trying to stand on a wobbly stick or something like that ? and then it indirectly helped SpaceX for their landing ?
