Tae Kwon Do’s Best Kicks, But Can They Do It Not To Both Fall After Each Kicks?

So far, those flashy flight kicks are good to see and feel power in every kicks but I seem notice that the kicker is the first to fall off the ground…

And when their kicks are successfully landed hit their sparring opponent, but can still capable of a quick kick back response too, but if the kicker is the first to fall off the ground, I think he is in great danger.

That if their opponent is a Muay Thai Kick Boxer or a UFC MMA fighter will surely grab the opportunity to ground and pound, preventing the falling Tae Kwon Do

not to stand back; but it is very hard to do kicks, especially jumping kicks without falling off the ground.

In a Foam Padded Tae Kwon Do ring match is never worry if you fall off the ground after kicking because there are no solid sharp obstacles on the ground, but if this happen on the streets where lots of sharp stones, cemented roads, solid cornered ground edges, it is very dangerous if you accidentally fall off the ground even though you know how to deal when falling.

I just wonder if a Professional Tae Kwon Do can do variety of kicks on top of the car instead of a foam padded ring stage.
Fighting on top of the car is the Western Boxer’s choice, as every punch

they delivered to their opponent, they never worry themselves to fall off the ground, and a boxer can do multiple rapid hand combinations of punches and keep on standing on their feet, so how can a Tae Kwon Do deal with those Western Boxers?

Those Western Boxers never care if their body hit by a Tae Kwon Do kicks, they just ignore it, since they know that after the kick, the kicker will soon fall off the ground, and a counter punching of rapid punches and a ground and pound if needed.

Here is the link of the best Tae Kwon Do kicks I saw on YouTube:

Just take note on what happens after the kick
Who is the one who falls first?
The Kicker or the Kicked?

So to fill the missing parts, those Tae Kwon Do Practitioners must include hand boxing, and ground grappling techniques to make them more a complete fighter machine.
Bruce Lee did this before, a combination of all the arts learned, just to fill the missing gap.
