I was driving my Tesla using Full Self-Driving (FSD), and my legs became a bit uncomfortable. I shifted them slightly and accidentally bumped the steering wheel with my knee, which disengaged the FSD. I was able to regain control immediately, and nothing bad happened—just a jolt of adrenaline—but it made me think this could be a potential vector for accidents.
My thought is that there could be a more blended or assistive driving mode where driver input overrides the FSD, but as soon as the driver stops providing input, the FSD seamlessly takes over again—similar to how it currently works with the gas pedal. In such a setup, FSD would only be disengaged through intentional actions, like pressing the brake or pulling the right stalk upward.
