Cannabis and heroin were available over the counter at corner drugstores. And pneumonia and influenza were the leading causes of death. In 1910, the population of the United States was 92 million and the world population was 1.7 billion people. Today, there are more cars manufactured than their is demand for it. There are about 1 billion cars and light trucks on the road. The maximum speed limit in most cities is 30 mph, yet the traffic is so congested that the average speed is just over 10 mph.
