I’m watch a little of the F1 race on NBC. They’ve got infrared cameras to show tire temperatures. How long till NASCAR catches on?
They used to use it a few years ago at Bristol/Martinsville/Richmond on the Brake Rotors.
Depends on the Broadcaster, ESPN was 1st then Fox used it for a while.
They used to do DoggyCams/and under car on Suspention or inside Tar Beads.
F1 was going from one to the other and then the last few Races went to an overlay blend.
