One-shot quali. Bonus: get rid of the dreadful fucking sprints.

Edit: No, wait! I thought of something even more impactful. Stop fucking zooming in on the cars so much! It’s gotten ridiculous. Most of the time you’re seeing about a quarter of a car, you can’t even tell which corner it is. It makes it feel so slow, and it’s sooo much less enjoyable than in the olden days. I want to see cars going around a track quickly, not some bullshit advertising for some company I couldn’t care less about. Ffs, just stop it.

The rule book.

Remove the hybrid engines and return to normally aspirated petrol engines.

Separate constructors from teams - I'd love to see the whole field in near-identical cars only differentiated by setup and driver. Alternatively balance of power rules like Imsa could make racing a lot more competitive while keeping constructors around.

Not sure how but needs to be more competitive so that driver skill was more important.
