So I saw that my car offered up all sorts of useful diagnostic information for self diagnosing stuff. Was very excited and went to look at it for a generic fault without having to get software to tell me what the fault is. I thought "it's stupid it has fully functional computer display yet tells me basically "contact a dealer, but it's safe to drive" instead of what the problem is. Then I find out that because I'm in the USA, the company keeps it to themselves...
So if they see value in treating regions differently, they will absolutely go out of their way to screw over the regions that will let them.
