When I first moved to Europe nearly twenty years ago, I realized the smallest cultural differences could be the most telling.
For example, consider the topic of measuring the gasoline/petrol mileage of automobiles.
Americans measure their fuel mileage in miles per gallon. It answers the question: how far can I go?
Europeans measure their fuel mileage in liters per 100 kilometers. It answers the question: what are my requirements?
Surely I am not the first one to recognize this?
