You maybe have seen cyclists standing on their pedals at intersections and wondered what they’re doing? Besides showing off and not wanting to clip out of their pedals, it’s called a Track Stand and comes from the sport of track racing. See the video below, starting at 3:38.
It’s done in a race to psyche opponents out, like gunslingers waiting for the other to flinch, and at a championship level.
Like any pro or messenger, they make it look easy and it’s not. I’ve seen Mark V Track Stand any bike, including folding and cargo.

Some industry bros do it dressed like a farmer and it’s a prop in a drinking game. You’re supposed to chug beer until the stand stops.

Check that video out again again, see how they go from a near complete stop to 40 mph in the sprint. You’ll see another cyclist Track Stand at a light, but doubt he’ll hit 40 MPH to the next one.
