For the most part you measure things in metres, kilograms, and litres. Feet and inches are used almost exclusively for describing the height of people or small objects. The people who appear on the most popular talk shows are mostly entertainers, politicians, or rather strange individuals. Certainly not, say, authors. You drive on the left side of the road.
Traffic lights exist only in the big cities.
If you're a pedestrian you watch out for your own safety. Cars are a luxury of the rich. The police are typically not armed, unless they are guarding VVIPs, in which case they might tote submachine guns. If a woman is plumper than the average, it improves her looks. The midday and evening meal are equally light.
