It's that "precise control of the manual" that's enabling. Presumably we'll see the same thing with fully self-driving cars in the future. This is, a mature self-driving technology should eventually out-perform (unmodified) humans, but even then, when there's no argument for manual-driving's practicality, some folks'd probably want to drive manually anyway.
