Proper way to set a RigidBody's maximum velocity

I am trying to gradually accelerate a GameObject with a RigidBody attached until it reaches a maximum velocity, at which point it becomes unable to gain any more velocity.

  • I know I can simply reset the object velocity to an arbitrary maximum velocity every frame if it overshoots, but I've repeteadly heard that manually setting an object's velocity is a very bad practice in the context of Unity's physics system.

  • I am also aware that in a physical sense, objects don't have a
    "maximum velocity" and that such a
    thing will always be artificial.

I can think of several ways to achieve this, but given these limitations, I would like to know if there's a standard, optimum way to do this.

The 'proper' way is to limit magnitude rather than velocity elements. This is, of course, dependent on the effect you are trying to achieve.
