I would skip auto ISO if you can avoid it, but my experience with Canon 6D and 80D may not fit your experiences with auto ISO. If the weather/light situation looks to be consistent, my first choice would be for full manual, setting shutter speed, then aperture to taste, and then picking the ISO.

My experience with shutter speed priority is that the camera will first adjust the aperture to meet the exposure requirements. It seems on my Canons that it's manual mode that can freeze both aperture and shutter and force the camera to adjust ISO to meet exposure. This would be my second choice, if it's a changing light situation.

Good luck, no matter what you choose.

If lighting is not even, option #3: auto ISO, set shutter and aperture manually.

As Tex-s alluded, camera models can work differently from brand to brand. Test shutter priority to see if it only adjusts aperture 'til it reaches widest or does it change ISO also. For the subject, distance and lens, how wide an aperture will be acceptable?

Shutter priority + auto ISO or full manual with auto ISO. I would personally prefer the shutter priority + auto ISO as that would allow me to use EC to control exposure which on my cameras is easier than using the lens aperture, but no big deal one way or the other.

It partly depends on whether you’re panning with the cars or shooting stills in the paddock/pits/starting line. Personally, in either case, I like manual with auto ISO since my camera allows EC correction with auto ISO (not all do).

If the cars are rolling past billboards or displays that might alter the metering in a bad way as you try to follow a car, I'd say full manual.

The best answer is not one you will like - it depends. There are too many variables to provide any useful guidance. It's best to be fully versed in both and possibly other approaches and be able to switch it up as necessary. I've shot race cars at 1/30 sec while panning, and at 1/3200 to freeze everything in the shot. At the end of the day, it depends on the conditions and the photographer's skill level and familiarity with the camera and lens.

Auto iso with manual shutter and aperture but regularly check histogram and be on look out for blinkers. Beware of backgrounds that may throw exposure off. Try it for a few exposures and see your results.

Go to a nearby highway and do some practice shooting.
See what you get. See how much motion you want in the photo.
Easiest way really.

I use shutter priority, manual ISO. I shoot birds in flight and my rear wheel controls the ISO, so in early morning shooting I can turn the dial to keep my shutter speed up where I want it. Easy Peasy.

none of you are talking full manual. for full manual,
1 pick a iso setting.
2 from a chart or your memory pick a shutter speed and apterture
3 set the camera and shoot.
anything else is meter assisted.
from the civil war until the early 1900's manual was all they had.

If you understand lighting, you'll never have to use auto regardless and you'll spend less time sitting in front of your computer. My camera is always set on M.

If you own a truly modern camera, such as an EOS 5DIV or EOS 90D, you'll know camera technology has advanced to the best of all worlds. Specifically, Exposure Compensation (EC) with AUTO ISO in Manual. You'll determine your shutterspeed and aperture combination in manual and then place the meter to the right with EC managing the ISO. Then, shoot away, adjusting the shutter and / or aperture while the camera dynamically maintains the exposure via the ISO. This is the Pro's Professional Mode.

I would use shutter speed and auto ISO with the aperture pretty wide open. The shutter speed would depend on what you are trying to achieve. i.e., do you want to freeze the scene or show motion.
