There's a company called "Sports Media Technology" SMT that has some nice integrations with the NHL (Hockey). https://www.smt.com/hockey#techinfo
They put emitters/sensors in the hockey puck as well as on the players. The data gets processed and displayed on video for audiences as an "augmented reality" experience.
My understanding is that the puck has an infrared emitter that is tracked by sensors in various locations around the rink and this can locate the realtime position of the puck. The players also have sensors/transmitters and this makes it possible to have really responsive position tracking (the video in the link shows how it looks quite nicely).
I suppose the speed and erratic motion of a hockey puck is not unlike that of an FPV drone.
There's a big difference if it's being tracked outdoors or indoors - depending on that you can use different technologies. Another thing is if you can use GPS (no local receivers/sender posts needed) or something like UWB - where you need to deliver coverage for your sensors, does not sound feasible for a NASCAR track.
SMT (currently) provides the telemetry for NASCAR, including 100Hz GPS location data, and those are regularly going >190mph at super speedways. It's not typically erratic but it works very well in any case.
