Do not reach through steering wheel while driving for remote on dash. Even if it appears to be safe. And especially, do not reach through steering wheel when turning a corner, or say, out of a driveway.
Such behavior could result in collision or bruised arm. If one does not experience collision, chalk this one up as lesson learned.
Meanwhile, assure co-workers that experienced near collision with hillside while sitting in cars behind you, that yes, you are indeed a safe driver. Ice arm.
