That’s right, we’re back to being a traffic blog again.
(Fantastic news, by the way: Back when I first wrote about highway traffic, it took forever to google a picture of a “diverging diamond intersection,” you’d get all articles about diamond intersections that just had the word “diverging” somewhere in them. But today, when I needed a picture of a normal, bad, diamond intersection, googling “diamond intersection” got me fifty pictures of diverging diamond intersections before I found a classic diamond.)
