Except some people want to win and don't care about their own personal performance.

Yeah but for the brief time window (which is probably coming to an end right now) where getting your name on the leaderboards was still worth it anyway, because people had not yet realized that the game is over, players will use the car anyway. Now that the game is over, leaderboards are meaningless, so we will figure out ways to move past that (like playing with people who care). But that will change the game in unavoidable ways: the tiny, fragmented scale will give less incentive for creators to come up with massive intricate complex challenges (it would be like hoping Bethesda would make Skyrim for a handful of die hard players). And soon, maybe on a few years, people will invariably start questioning whether it even makes sense to waste their time with this hobby if learning CTF skills is basically useless in an AI dominated world. There are still people learning Assembly for fun, but almost nobody does Assembly programming challenges as a hobby.
