Yup. Complex adaptive systems, including road networks, do what they darn well please. Hence Hayek and his Fatal Conceit. On the other hand, Venus transits always come in pairs (conjugate pairs?) with two in eight years and then the 122 year interval to the next one. Tonight, that rare performance of Sousa's "Transit of Venus" March. Looks like the weather will hold off for the concert.
