Those are good points. However, with the Olympics’ having boxing, wrestling, and hockey, I’m not sure about the concern for humans. Maybe potential tv viewership is the only criterion.
None of those sports has the potential impact from a single hit that a lance does! I speak from a scientific standpoint as well as just a spectator.
They have fencing but it is ninny. They’re in full armor and have to stop every time a strike is made. Kind of hard to stop the horse and pull back, and I don’t know how useful a flexible lance would be.
