yep. some more than others. While this is a black belt test, the chances that a gang of tkd students are going to attack you in the streets is very small. For self-defense this should have contained some of the things that one would expect to see in the streets, like punches lol.
lol that would a butt kicking because only the attacker would know that it's training. The victim would think it was real and do things they may not have normally done in a scenario.
Sort of like how pranks go bad, where one guy jumps out to scare another and gets punched in the face.
but like you stated there is always limitations. There's no getting around that.
