I got caught Wednesday night in the national pre-Thanksgiving traffic jam. As I was approaching Baltimore, an electronic signboard announced:
Of course I immediately thought: But everyone will read the sign and take I-695, so that road will be jammed too. Then I thought: But everyone who reads the sign will realize that everyone else will also read the sign, and so they’ll not choose 695. Then I thought….
Hmm. There’s something familiar about this problem.
I’m not telling which road I took, but I can report that it was the only congestion-free segment of my trip.
