I am trying to rotate a steering wheel inside of a car. But when users touch the steering wheel, the wheel offsets... moves off of center. I added constraints to no avail. Is there a way to lock a steering wheel in position?

As an example project, I dummied up a block with constraints for rotation (I found that two constraints work better than one, like on a door) and so it should only be allowed to rotate. However, that is not functional. You can rotate it in fact, but as soon as you push on the block, especially at a point near the center of rotation, the block jumps all over the place. If you push correctly, the block will bounce around jerking back and forth and damping seems to have an effect, but very small.

Here is a link to this super simple project.

So, my question is simple I think. How do I setup an intractable steering wheel such that a player can touch it (how do I setup the hand too) and the worst that might happen is that the steering wheel might rotate.
