Americans really dislike learning and being inconvenienced.
it’s worse than that-- we have gallons of milk, but liters of soda. we drive in mph, but run in 5K. science and medicine weights are grams, but recipes call for ounces. want to fix an american car–hope you have both metric and “standard” wrenches
more like we’d rather stay with the stupidness and inconvenience we know rather than change anything, no matter how much better it would be
