Today, people get upset when the car ahead of them is driving 25 in a 25mph zone. I mean, how dare this idiot ahead of them slow them up on their way to the Walmart? In the unmarked road case, people will eventually learn to act in their own self interest, which probably means zooming around the slowpoke. This will result in (a) very little, (b) a head on collision (c) the sudden termination of the 8 year old that was riding their bike in the road - which is why the original idiot was driving at 25 in the first place.

I seem to recall hearing about this approach in the mid 90s; I wonder if it came about as part of the same research mentioned in the article.
