Government as a Religion

[Angrboda]

I would hate to drive in Koolaid's country.

Some people will decide to drive on the right, and some people will decide to drive on the left.
It will be this way since there can't be a single person or group above the individual, so no one will have any actual authority to tell people which side of the road they are allowed to drive on.
You "hope" people will agree to drive on one side or the other, but again, without authority above the drivers no one can ever enforce driving on one side.

I can see the road casualties and fatalities now.....

I've come to the conclusion that Koolaid is Chaotic Neutral.

Not to spoil a good bit of sarcasm, but there's good evidence that the rules of the road emerged independent of any forced uniformity, largely due to the mechanics of transport at the time, and when those mechanics changed, so did the consensus view on which side of the road to travel upon. Furthermore, I suggest that such a system would be meta-stable in the way that spin glass is in that even if there initially were a random distribution of conventions regarding which side of the road to drive upon, it would quickly converge on one or the other solution as a simple practical result of the higher cost of bucking the consensus. (Not to mention the fact that there are independent incentives to cooperation regardless of any higher authority. As a practical matter, it's unwise to assume that any simple system will not exhibit emergent self-order, independent of actual evidence.)
