One is driving on a two-lane road. A sign indicates that in one mile the right lane will be closed. Most drivers begin moving over into the left lane. But a number of drivers continue driving in the right lane because, as the left lane becomes more congested, traffic in it becomes slower; drivers in the right lane can continue moving quickly. Drivers in the right lane count on being allowed into the left lane once they reach the actual spot where the right lane is closed. They can, it turns out, fairly reliably depend on being allowed by some driver into the left lane, so they generally in fact make their own trip quicker than if they had moved into the left lane upon seeing the sign.
Drivers who stay in the right lane are effectively sending the message that they believe their time is more valuable than that of drivers in the left lane. If that were all that was involved, this situation would be like the other instances of rudeness with which one meets in a day. But there is more. This is a compound rudeness. Drivers in the right lane are simultaneously being discourteous in the aforementioned way to drivers in the left lane and implicitly communicating that they regard them as saps: behaving poorly while banking on the good behavior of the very people toward whom they are behaving poorly. Indeed, their actions are triply offensive, since the slow speed in the left lane is caused in no small measure by the left-lane drivers letting right-lane drivers in at the last possible point.
And one's fellow left-lane drivers are saps. One is perhaps more frustrated with them than one is angered by the right-lane drivers. All that would be necessary to thwart this churlish behavior is for each driver in the left lane to follow the car in front of him or her closely, so that right-lane drivers have no opportunity to enter the left lane and instead sit motionless at the point where their lane ends. But that would require a level of communal resolve that does not arise in such situations and that one has no hope of even attempting to secure from the cabin of one's own automobile. The only reasonable response to the incivility of right lane drivers is to create a disincentive to their behavior, and yet one watches helplessly as left-laner after left-laner exercises a misguided and self-demeaning politeness rather than reason.
Through all the period during which one is already suffering a delay, one is simultaneously being vexed by repeated instances of a maddening combination of discourteous and unthinkingly over-courteous behavior. One sees--and remember, has an enforced leisure to witness--maleficence rewarded; virtue punished; the clear dictates of reason unheeded and inert.
