Much has been said of the Tesla's Autopilot being similar to that of an airplane. As I drive with Autopilot, I find myself wanting to nudge the car slightly within a lane. I know this can be done to a degree with the steering wheel, but it easily disengages. I'm proposing something more subtle and accurate. My thought was that an optional dashboard "app" would allow one of the scroll wheels to "trim" the car's position in a lane. Each click of the wheel could be, say, 2 inches. If you scroll up, the car trims to the right. If you scroll down, it trims to the left. This data could be used to help teach the system more accurately where you'd like to be in the lane. (Imagine the accuracy of the maps being adjustable by a couple inches from the fleet of expert drivers.) But, more importantly, it can keep you (as the "driver in command") in a position that feels safest to you. Of course, this would never allow you to exit a lane and actually steer, but I envision it allowing you to override Autopilot's lane selection up to a foot either direction within the lane. Trim is commonplace on airplanes and I feel it could translate well here. Any thoughts on this?
