To be fair, airplanes are not comparable to automobiles. Flying an airplane does not actually require nearly the amount of attention driving a car does. The sky is mostly empty, and planes will generally continue to fly straight ahead even if you let go of the control yoke. If you look away from the sky while flying, you're highly unlikely to swerve out of your air lane into another plane, rear-end a plane in front of you that braked suddenly, T-bone another plane at an intersection, or fly into a pedestrian using a crosswalk.
