First come, first served.
That’s the essential protocol that exists both in day-to-day life and on the road.
Of course, there’s always someone who just has to do their own thing. That one little goose who decides “to hell with it, south is too crowded, I’m headed north.”
The area where this defiance is most troubling is with the nation’s stop signs.
Common sense tells you when two cars approach opposing stop signs, it’s the one who gets there first that gets to resume its journey first. The other is compelled to sit back and wait its turn.
When two cars reach those stop signs at the same time, well that’s another matter entirely. That just becomes an ugly war of attrition where the owners of both vehicles end up pointing wildly, cursing the other to the depths of hell, each inching forward until someone finally snaps and speeds off into the distance, likely with one finger raised proudly in the air.
It’s not perfect, but by god it’s the best modern man can do, unless you want stop signs on every intersection. First come, first served. It’s written in our DNA, ground into our very being since kindergarten.
