Based upon what objective evidence? Gut feel does not count.

There are lots of engines of various types that still show good crosshatch on the cylinder walls at high mileage, certainly at 250k. What basis do you have that the cylinder wall wear is the point of issue or determinant of longevity???

Interesting. Travel in Europe much?
Funny that you use the UK as the primary example. Their highest speed limits are 70 MPH, per here:
https://www.gov.uk/speed-limits
And the UK is roughly the size of Oregon, Wyoming or Michigan. Not huge, so not long distance high speed driving.
Even Germany... Ever drive the Autobahn? Yes, there's no limit, but routinely at interchanges the speed limit appears and drops speed rapidly. So there's something to be said about big brakes and high acceleration out of the speed zone, but with 82M people in a country that is 85% the size of CA, the distances arent that far/long.

So longevity is determined solely by oil viscosity and how hard you are choosing to run the vehicle will have no impact?
Understood that many older manuals say that if towing or routinely carrying heavier loads, higher viscosity may be prudent, but it needs to be understood that there is an engineering balance between being too lightly loaded, too heavily loaded, viscosity of lubricants, time at temperature, etc. Increase in any one parameter can only be bandaided by something like oil viscosity, or fully fixed by utilizing equipment that is more capable.
