I don't think driving looks easier than untangling. You can untangle nice and slow with little outside involvement. When it comes to self-driving at 25mph without traffic, it pretty much is a solved problem.

I think this untangling problem gets underestimated because people aren't consciously aware of what they're using to analyze and address a tangle. The input is not all vision - you've got sensation in your fingers giving you feedback with which you update your model of the problem as you progress. The operation varies in strength depending on so many factors.

At the point you have enough sensor input, enough force application variability, and the power to process this in the ballpark of real-time (comparable to a human brain), you now have a being who's going to advocate for the removal of slavery and the application of rights.
