>>2716599Different anon but I spend a lot of time at road courses. Go to Laguna seca if it's near. Most road courses let you wander around the center of the course/paddock and up to the fences. The best spots usually require credentials. Take a telephoto for the racing and a decently wide lens for in the paddock.
If you want good light look for endurance races that go into the night. Villeneuve is the only track in your list I can think of that might restrict movement around the track, but I'm not sure.
