I couldn’t disagree more. F1 is constantly evolving with teams coming and going and the ownership of teams is always in flux. Look at how many people now have shares in racing point. F1 is a business just as much as it is a sport. The Williams Family (as much as I fully admire ALL that they have achieved and it really is amazing) were not able to keep up. Their “old school” model didn’t work anymore.
F1 has been reinvented around the requirements of motor manufacturers. The engine rules about 'relevancy' are supposedly about an F1 engine which resembles something in a road car -- so a six cylinder with a turbocharger is logical and kinetic energy is easy to follow.
But that extra thing -- MGU-H, basically an exhaust turbine which charges up the same batteries as MGU-K, the brake charger -- was laboratory tech until the F1 rule makers added it to the rules. I've read scientific papers from the the 1920s to the 1980s about MGU-H theory, and 100 years later it is ridiculous technology for a road vehicle. It is 'relevant' for the rules but it is irrelevant to any road car. And ridiculously expensive. How many companies is it -- four, I think -- have built an MGH-U? Well done to them, but so what?
When you take away the MGU-H, there's a possibility that an expert in combustion engines and an expert in electrics might team up to build a competitive F1 engine on a sensible budget.

Never assume that F1 or GP racing interests car manufacturers. Ferrari is the only team that has never walked away from F1 or GP racing, and we have to give an allowance breaks.
