In that regard, why would you want to run an inadequate oil that doesn't provide sufficient lubrication for your engine during the emergency times when you really need it? Sure, 99% of the time, the extra overhead won't be needed, but that 1% when it occurs will destroy your engine.
Also don't get cold-start viscosity and cold-start flow mixed up with warmed-up engine requirements. Why settle for "good enough" when "way, way better" is available?

That's only going to be true if there are problems or lack of proper maintenance. If everything is functioning properly overheating is not going to occur with a water-cooled engine no matter how hot the temps or how little of airflow there is.
I agree - use an oil that can handle an overheating situation if it ever occurs. It's not
that much more expensive or hard to get.
