The reason these series always get compared is because Indy’s tight rules make it less compelling while F1’s more open rules make it less competitive.

WEC (and IMSA a bit) solve those problems but they have so many drivers and teams that it takes a lot of dedication to follow along.

In the end you end up wondering if your favorites could hack it in the WRC.

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.

Watching a winner of 80+ NASCAR races ride along for a hot lap of the Australian Bathurst 1000 course is fairly entertaining ... https://www.youtube.com/watch?v=kLkLtBkUVuo

V8 Supercars on Mount Panorama don't disappoint.

I think that an ideal race league would use WRC-inspired homologation rules and little else (except for some safety features)

Any chassis size. Whatever aero you want. Any engine size/configuration. The only constraint is that it needs to be something you can put into production.

we’d get to see a Cambrian explosion of weird race car variants that would make race day strategizing wild. and we’d really get to showcase cool creative engineering. And we’d eventually see the benefits of that engineering trickle down into normal production cars we all drive

It's been done. Look up the Can-Am series. At best, it would last a couple of years until the cars got way too fast for the tracks, and the manufacturers were no longer prepared to invest in it because there was no commercial return in it for them.

The idea that there is any significant relationship between what makes a good production car, even a sports car, and a racing car was always dubious and today is frankly nonsensical.

The way to make a car fast round a race track basically comes down to the amount of downforce it can produce, and the power of the engine. Downforce is almost completely irrelevant to road driving, as taking corners fast enough to generate cornering forces of over 1G is frankly suicidal on the road.

As for engines, aside from the fact that the internal combustion engine is doomed in road transport (despite what the current administration thinks), producing an engine with performance that exceeds what even good drivers are capable of handling without electronics doing the job for them was solved at least 20 years ago, and continues to be a solved problem despite tightening of emissions standards.

In any case, while lighter, smaller, lower cars remain the preferred option for motorsport applications, all anyhbody wants to actually buy, particularly in the United States, is gargantuan SUVs and pickup trucks, which makes any application of motorsport technology for the road moot.

I favor little regulation and tight cost caps. Example: you get 100 millions, 100 kg of this kind of gasoline per race, do whatever you want.

Any chassis size is probably not a good idea because cars collide with each other and they must do it safely. So maybe rules should define a box that cars must fit into, with the parts that get in touch with other cars at given places and with given shapes. Example: we don't want spear like nose cones at the same height of the heads of drivers of other cars. No halo can protect against that.

The problem with little regulation is that manufactures will be frightened to enter because it's easy to have a championship in which the one with the bright idea wins all the races and the other ones are scattered 2, 5, 6, 7 seconds behind.

We had something like that with the CanAm https://en.wikipedia.org/wiki/Can-Am

A lot of innovation and crazy designs.

I'm new to racing, but can you elaborate on this? How are F1's rules "open"? They seem just about as strict if not more so than IndyCar to me? At least I don't think IndyCar has "ahead at the apex" rules?

I'm glad I'm not the only one. Screw "Grill the Grid" or whatever nonsense they're doing on YouTube now; let's see the F1 grid do a rally.

There are technical regulations and sporting regulations. I'm not very familiar with IndyCar anymore but my feeling is that F1 got stricter on technical regulation but IndyCar is even stricter: only one chassis and more standard parts. However F1 sporting regulations seems to be tighter. The classic clash between Villeneuve and Arnoux in 1979 would be unthinkable now. Not only they would be black flagged and stopped for a GP but no driver would even think about doing those kind of overtaking attempts.
