That's not my point... as others have pointed out, it's a legal document. All I am saying is that this is a pretty universal "industry standard" that pretty much every car maker has adopted.
You know what's funny? Go on Google and search "______ break in period", insert your favorite car manufacturer. All the various forum threads are just like the ones on here, with people for/against a break-in period and generally everyone following the same procedures (500-1000 miles of varied RPMs, no redlining, etc etc)
The only way to determine if this works or not, is to separate a large enough sample set of owners who have owned their cars for over 10 years from new, and separate that sample into two groups of people who did a "recommended break-in procedure" and those that did not. And then, analyze the fuel and oil consumption of the cars after 10 years, as well as average maintenance costs of said vehicle.
I really don't think any car maker has this type of data, and until this data is published it's all just my word vs your word on the internet.
