I don't think it is easier than driving a car- somehow it feels even harder. Driving is a very well defined task: you are sitting in a precise position from which you get a well defined and purely visual input, and based on that you operate on three or four analog commands- maybe 3 degrees of freedom in all? And while the visual environment can be complex, there are situations- such as driving on a highway- in which the environment has already been reduced to a schematic version of itself: a wide, mostly straight road, with lanes and sides marked, and all other objects on it conveniently vehicle-shaped. Cutting hair is none of this: your position constantly changes, and the stuff you're operating on is irregularly shaped and constantly moves and tilts and turns. You need to manipulate small tools relying on a mix of visual, touch and force feedback, and you need to interact with hair, which is probably difficult to model. I don't know much of surgical robots, but I assume they're either executing pre-planned operations with a single tool on a completely still subject and/ or they're being controlled by a human surgeon.
