Miles per hour first came into common usage with the regular stage coaches in the 18th century, as running the stages on time required a timetable. In the early 19th century with the advent of the railroads speeds became significantly higher, though at one time many people thought that all the passengers would asphyxiate if the trains went at over 20 mph. This myth was quickly dispelled as trains were soon travelling at 50mph and above and the passengers were surviving the experience.
