Is blender able to do nested animations? It’s basically an animation inside an animation. For example, the wheels on a car spinning would be the nested animation to the wheels turning. That is a pretty rudimentary explanation of nested animation but I’ll take for granted that people who know what nested animation is will know what I’m talking about.
Basically - yes…
Like, in the example you gave, you could animate a wheel, you can set that animation to repeat forever (or not - you can control how and when it loops with the action editor) and then you can animate the position of the car - as the wheel is parented to the car, it will move with the car.
