THUG 1 Moscow tank glitch - found!

Briefly, there's a spot on a tank in the Moscow level where you can grind and "Kissed the Rail" repeatedly but not move, allowing you to rack up as many points as you want until releasing the grind button. I asked about this a couple months ago and apparently no one had heard of it before. I haven't found references to it elsewhere online, either. So, after 20 years of assuming it was common knowledge, I have some videos.

• Non-maxed character getting easy stats: https://youtu.be/GjoW_0WQPEc
• Suddenly bailing for no apparent reason: https://youtu.be/fQot7_ajlW0
• Bailing even with the perfect balance cheat: https://youtu.be/liY8A1PFa8Y
• Getting such a high score that it goes negative: https://youtu.be/73tEEGnAzgk

More explanations in the video descriptions. This is on GameCube, by the way; I don't know if it also happens on other platforms. Enjoy!
