it says a higher oil (doesn't specify what weight) can be used in extreme situations like tracking. Last time i checked daily driving isn't extreme.
Also that entire section is an example explaining what oil weight is/means not necessarily specific to the vehicle either.
In the section before that, that is specific to the vehicle it clearly states.
recommended viscosity 0w-20 (no other weight listed as recommended such as 5w-30)
and states
If 0w-20 is not available 5w-20 may be used (doesn't say 5w-30), but MUST be replaced with 0W-20 on the next oil change (indicating its not ideal but an alternative in a pinch).

You are being a little too literal about an oil weight that's only slightly higher than 0w-20. Though I don't disagree with you. RToyo quoted the links in other regions that specify 5w-30 that was referring to, if you want to be literal.
Otherwise, there is no big deal in running 5w-30 for us, the oil is not different enough in thickness to cause any damage. Though I have no proof of this, you can certainly read into the hundreds, or even thousands of people on this forum who run higher weight oils without issues (I am referring to the moderate ones such as 5w-30 or 0w-40, etc). Besides, the argument here is not what specific oil weight he should choose, but rather that 15w-50 is WAY beyond any oil spec he should be running.
