From Mind Hacks: Experienced drivers perceive the road differently Experience drivers have more peripheral vision than novice drivers … and thus are more likely to perceive and anticipate danger and adapt to changing circumstances on the road.
The problem is if we don’t let drivers on the road until they are experienced, no one can get experience, unless we have really good simulators the way they do for pilots, or better yet, like in Orson Scott Card’s Ender’s Game.
