AI Learns to Speed-Drift by Itself (Bonus 5/5)
🕑 Added 2025-10-03 09:00:06 +0000 UTC
Here’s a visualization of the AI progressively improving its speed-drift technique on A01. I originally planned to include this footage in the A01 video, but later decided to cut it to avoid making the video too long.
During training, the AI gradually learned to keep its drift angle close to the optimal value (red arrow) with increasing precision. We can also see how it progressively adjusted the timing and position where it initiates the drift. By the end, it was starting the drift almost exactly where human players do.
I also included a comparison between the AI’s speed-drifts and the human ones. As you can see, Eddie’s run has a much less precise speed-drift than the AI.
Speaking of human records: in the A01 video, I mentioned that Eddie’s 23.79 was recently beaten by Rollin with a 23.78, which was already quite a surprise. Well, against all odds, A01’s record was beaten again only 10 days after uploading my video! This time with a 23.77 by the player Axell. An insane achievement, which shows once again that A01’s history just never seems to end...
