Does it mean car manufacturers will be correcting their oil recommendations with better/proper oils and making you regret you followed the manual during all this time (trying to 'not void' warranty)?

on a warmed up vehicle the difference between 0w20 and 20w50 might be a couple percent.Does it mean car manufacturers will be correcting their oil recommendations with better/proper oils and making you regret you followed the manual during all this time (trying to 'not void' warranty)?
now during warmup phase in which many engine parts contribute to fuel economy it might have slightly more impact.. at low winter temps.
I'm not a thicky or a thinny but I do want to be sure my engines have adequate protection.
A guy on the outback board compiled all the UOA with the 2.4T engine and from memory ... 65% were out of grade thin.
In an engine that IMO is boarderline to use 0w20 oil in anyway.. it gets away with 0w20 by running with relatively cool oil temps.
if they were hotter such as a B58's 220f+ temps you couldnt run 0w20 in a turbo FADIT24.
I expect my m1 5w30 EP to be well into 20 grade territory when I UOA it later this year.
The expected mpg loss is less than a percent. to run m1 ep 5w30 vs 0w20.
so the risk/reward vs the penalty is quite good to me.
But I think we might be getting off topic now

I want to see "mid tension rings" instead of low tension rings in up coming cars. I will give up the .01 mileage loss
And that's properly addressed in the new directive. CAFE is a fair game here too.
(e) to eliminate the “electric vehicle (EV) mandate” and promote true consumer choice, which is essential for economic growth and innovation, by removing regulatory barriers to motor vehicle access; by ensuring a level regulatory playing field for consumer choice in vehicles; by terminating, where appropriate, state emissions waivers that function to limit sales of gasoline-powered automobiles; and by considering the elimination of unfair subsidies and other ill-conceived government-imposed market distortions that favor EVs over other technologies and effectively mandate their purchase by individuals, private businesses, and government entities alike by rendering other types of vehicles unaffordable;

I personally don't think the majority of people care about fuel economy. Everyone wants bigger and bigger vehicles . Large 3 row SUVs . Trucks that aren't needed but wanted . Which is fine , you should be able to drive what you want . 20mpg seems to be the magic number . Less than 20 and it's a guzzler , more than 20 it's all gravy . My wife thinks 20+ is great mileage.

That's what I care about....mpgs
If you are on the road all of the time it's very important.
In particular, taller and taller vehicles so they can see over traffic. When will it end? When they don't fit on Storrow Drive in Boston anymore?
Yup, I think OBD2 was introduced in 1995 for the 1996 model year.
There was an article at the time saying that a new car polluted less running than a '60s car did just sitting there not running. (No evaporative emissions control.)
There were also claims that, in a typical large urban area, the exhaust coming out of a modern car was cleaner than the intake air.
The improvments since then have been relatively minor.
The biggies were, as I recall and in approximate order, PCV valves, electronic ignition, unleaded fuel and catalytic converters, evaporative emissions controls (charcoal canisters and associated plumbing), O2 sensors and feedback carburetors, TB fuel injection, and finally MP fuel injection.
The air pumps were evolutionary dead ends.
I'm not sure DI is worth it.
All that to say, I could see scrapping older cars years ago for air-quality reasons, but think that anything built in the last almost 30 years will be pretty clean if in good running order.

Think it’s much to do with how much driving one does - we don’t pile up the miles yearly - so it’s a minor consideration …

I think stop/start was a sign of too much meddling
Yes, they will.
CAFE standards force manufacturers to sell vehicles that get high MPG. That frees up the manufacturer to sell higher cost and margin vehicles that get worse MPG. It's all part of the CAFE formula.
And speaking of formula, one of the reasons the mini truck is gone now is because of CAFE. Small footprint trucks are forced to get stupid high MPG, while large full size trucks aren't. The CAFE formulas are heavily flawed.

EVs are a fraud. They actually have more emissions than ICEs because they need new tires about every 5k miles. The rubber being emitted into the air is much worse than modern ICE emissions.
I believe much of the reason for CAFE is to eliminate personal vehicles because of EV high cost and poor ICE reliability due to constantly moving CAFE standards. Besides who needs a vehicle when we all will be living in 15 minute cities? See LA 2.0.

Enough of the bickering about off-topic stuff, or this will get locked.

The only thing that I really don't like about the Maverick are all the nannies, that are relentless and redundant. They fixed the grabby brakes so this is all I have to gripe about.
That's really a simplistic view of something very complicated. He's in charge of federal land where oil can be explored and extracted. That is a major component of a much larger energy plan, of which he is a major contributor and has to be neck deep in it, which includes a major understanding and decision making role in the big picture. He's been a part of this for longer than any of us might think.
Me personally, I’d rather take 1mpg less, and not have to put lifters in my truck. That 1mpg difference would take a very long time to equal the cost of a repair like that.
CAFE should give weight to the longevity of the vehicle. Not needing to scrap 1 to built another has to improve air quality. I also always felt the total pollution produced to manufacture a vehicle should be a factor. If the pollution produced to make it is greater than the pollution saved during its life its a false economy.
