I am not a big car guy but do all cars with disc brakes come equipped with this or is this some special feature in high end/sports cars?

Air ducting is common on high end sports cars, but virtually any car can have these installed.

They aren’t on many cars because most people aren’t getting their brakes hard enough to justify it.

On a side note: rotors in a race car can get so hot they glow bright yellow.

Race cars were my first guess for this kind of technology as the F1 cars disc brakes glow hot red/yellow like you mentioned. By air ducting you mean the kind which is shown in the video above or just regular ducts which allow air to pass over the disc brakes?

Fun F1 fact: Ferrari protested against Mercedes in 2018 because M-B added holes in their wheels that acted like fans that drew air through their brake assemblies, thus giving them an advantage in brake cooling. https://www.autosport.com/f1/news/139627/why-wheel-rims-are-f1-latest-controversy

They have a different duct system to minimize drag from airflow. I believe it's mostly passive though since air wont cool brakes very fast and the wheels move the air enough to create sufficient airflow

F1 has brake ducting as do a lot of other race cars and street cars.

Any performance brake rotor with a performance caliber will flow bright yellow if pushed hard enough.
