Almost no sideslip / adverse yaw ?

[Anatoli-Kagari9]

In every video I've been watching there's almost no displacement of the "ball" in the turn coordinator, including when taxiing and making sharp turns on ground.

 

 

Inflight the ball stays pretty much centered most of the time.

 

 

Wonder if this is actually a characteristic of the real aircraft or some limitation of the current code of the turn coordinator ?
