"that was effectively stymied by the US auto industry." Do you have a source for that? Not implying its false. Ironically if you've worked on an auto built from the 90's (maybe even 80's (man I'm old)) onward, you'll find a confusing mix of standard and metric fasteners often within the same components - doors, etc.
