4 Armoured knight: So we really are travelling very fast, then?

For a very long time, the fastest that any human ever moved^[1] was riding a horse, about 40-45 km/h for a typical gallop according to results provided by a popular Internet search engine.

[1] Horizontally. You can very easily exceed the speed of a galloping horse by falling. If you fall a distance of just 8 metres, your velocity will be 12.5 m/s, or just over 45 km/h. Downwards. So there were probably plenty of people in history before the invention of powered vehicles who exceeded the speed of a galloping horse. It's just that most of them died shortly thereafter.
