Think Pinball for Roadway Design

As people crash around on the roads like bumper cars, perhaps it's time to up the funhouse ante. Let's design the roads like pinball machines with side bumpers on the sides of the roads & mushroom bumpers in the middle of wider roads.
Drop targets & spinning targets could provide driver information directly in the roadway freeing up sidewalk space & eliminating aerial clutter.
AND, as drivers spaz around like leaves on the wind, bereft of any tangible goal, the spinning rubber mat in the game, Fireball could be used in intersections, taking the pain of making decisions out of the driving experience.
