For what it's worth, the most entertaining circuit racing in the world happens at grassroots level featuring slow, cheap cars that permit a lot of drafting.
The faster the cars get, in the main, the less overtaking occurs.

V8 Supercars on Mount Panorama don't disappoint.

But while Supercars can be entertaining, they are in some ways a faster version of the categories I'm describing - they don't have much downforce and not that much mechanical grip either, so they're pretty slow in corners even if they are respectably fast in a straight line.
The bare minimum of downforce and grip in tight corners on a mountain pushes the skill requirement to, uhhh, over 9000.
I used to spend hours every day at 252 km/hr (156 miles/hr) 80m above the ground. That got dull fast as it was in dead straight headings for 20km or so at a time.
( Did have to keep an eye out for birds taking off over lakes, power lines, etc. though )
