Hate to say, but you’re talking out of your arse a bit. A 2010 (15+ years old) V6 Toyota 4Runner has a 16k/12 month oil change interval. This isn’t a new thing and certainly hasn’t changed in the last 15 years (other than more vehicle being designed for this I guess?). You’re free to look up the manual online. Toyota makes them available.
As far as Special Driving Conditions, I don’t think most people spend the majority of their time driving in them (as that is what they refer to). Those were 5k/6 months… and those are still 5k/6 months today.
Look up 2015, 2020, and 2025 while you’re at it. It hasn’t changed. And in both cases, it’s whichever comes first (months or km).
One of the best resale value vehicles on the road, btw.

In case I am totally out to lunch, your 2010 Toyota 4 Runner goes by the old maintenance schedule of every 8000 km's using the higher viscosity oils. The same goes for an 09 Toyota RAV 4 I have with a 2.5 L 4 cylinder.

The 2025 RAV 4 I have calls for a 0-W16 weight oil and 16k km's between oil changes. The old 5W30/20 weight for much older Toyota's means it's almost half as thin and needs to be changed twice as long? How much possible innovation has occurred for 4 cylinder Toyota's on an ICE engine from a lubrication and cooling perspective?
My basic, logical method of car maintenance is to just do a little more on the important things. Use quality oil, use factory filters since you really don't save money vs aftermarket. Change your fluids frequently within reason.
Decisions in the car business lately are geared towards making more money for dealerships and the automakers and that is beyond evident by virtually everything that is being done these days. Shut down competitive shops slowly and design things requiring more and more proprietary parts/service for more dollars.
It's not like this situation is unprecedent in other places too with executives overriding engineers. Boeing airplanes and their systems are a direct result of this as well and caused crashes and other concerns. If your asking me if 16-25 k oil changes intervals are in the best interest of the owner, I would respectfully say I highly doubt it and it's better to change your oil a little more regularly if you want your car to last a longer time. If you don't drive a lot or keep cars longer, than it doesn't matter and let someone else deal with the repercussions.
