If two people enter the shop together, and one of them is buying alcohol, they both have to be 21. You have to be 18 to buy cigarettes. It is fairly common that people drive drunk. It almost looks like applying a drug. In the West, people are better drinkers, and shops are better equipped.
Roads are straight, with almost no curves.
Cars are heavy, all equipped with automatic gear, and they accelerate slowly. It doesn t really matter, because people generally don't overtake. Moreover, it is forbidden on most streets. Everybody drives pretty fast, just about the speed limit, which is 55 miles per hour. No slow old drivers around.
