There is a train race. Just like car racers, you have train racers putting coal in the engine, pushing the machine forward the finish line.

At one point, a few racers are saying that they are moving at incredible speed and everything is "so hot".

As any train, you own the speed, not the track! At one point, a racer might say that the current speed is too fast if a sharp curve is coming, but that he cannot stop putting coal in the engine because slowing down might cost him the race...

That's what is happening.

N.B. I don't agree with AI LLM and all that, I am trying to explain as best as I could.

See the Skeleton sport too...
