I'd say they'd still be required. While their advertising says otherwise, GridGuide goes on a wonky-spree far too often, and some semblance of skill is needed to deal with emergency situations. Even Pilot Programs can have a BSoD and suddenly you're on manual controls.
It's like some airlines (From my understanding), the pilot mostly just sits there while the plane is on autopilot, but for the hard stuff or when things go wrong, he's gotta do his job.
Rank 0 skill means you passed your Driver's Ed course and got your license after one, two, five tests. Rank one means you aced your test the first time. After that, you're in the areas where you're a stunt/combat driver.
