Interesting, didn't know that the metric system was the the preferred system of weights and measures for United States trade and commerce by law!Ignoring your "utter ignorance and inexperience with motorcycles".
Ok, I'm so sorry I upset you with my generalisations about Americans and the metric system. And I realise that America is not alone. Neither Myanmar nor Liberia use the metric system, although every other country outside the big, beautiful wall use the metric system.
I know that some Americans have made some progress with some understanding of the metric system. Perhaps there has been insufficient time since the introduction of the Metric Conversion Act in 1975 for the majority to have gleaned any understanding however.
Here's some Americans in action to illustrate my point.
I think that "incredibly unwarranted" is a little strong, though.
Anyway, lighten up. Its a thread about hazard lights and I posted up how to fit them.
