To your point, we already have testing jigs for these sorts of systems in the automotive world for steering and suspension.

I can't find the video clip atm, but there's a neat (likely leaked) Foxxconn video that shows a really neat testing jig for Apple trackpads.

There's all kinds of automated testing in the world.

The fun part is that some of us (actually, in this particular crowd, many of us) already have a lot of what we need to get some automated testing done at home, and we may not even realize it. :)
