Closing speed is how fast one car is arriving at another. Closing Speed reads it from live timing, GPS and telemetry, and flags the next broadcast-worthy moment — a battle, a traffic conflict, a pit-cycle convergence — while it is still on its way.
Every class runs its own race, and up to sixty cars share the same circuit. The fastest cars arrive on the slowest ones again and again, and the moments worth showing are scattered across the whole field. A broadcast can carry one of them at a time. Choosing which one, in the next half minute, is the work.
The engine tracks every gap between cars, along with its confidence in the call, and marks where two of them will meet while they are still apart. The call comes first, the moment follows.
Where to look thirty seconds from now, and why: a developing battle, an inter‑class conflict, a leader about to hit traffic. One line at a time, easy to overrule on sight.
What happened to car #57 while you were away, and what is about to come together for it: the same event stream, read backwards.
Every prediction is logged as a decision episode: what the engine saw, how confident it was, what happened next. After a race, the log becomes numbers — precision, recall, lead time, false alerts per hour — wrong calls included. The accuracy of the calls gets measured, not just described.
