If you look over the fatalities that have occurred over the decades in the United States, you will notice a few trends. The first is that for most of modern American driving history, the number of people that have died in motor vehicle accidents in the U.S. per year has been over 40,000. There were even periods where it stayed above 50,000 every year.
Sometimes when you fall down, you might not be able to get up, especially when a serious injury such as a head injury or broken hip occurs.
The word "accident" has become to mean a whole of incidents that aren't actually "accidental." People who text and drive get into accidents. People who consume excessive amounts of alcohol get into accidents. People who speed, run red lights, and disobey the law get into accidents. But all of these cases aren't truly accidental, as the people behind the wheel of the car are responsible for their actions.
