## Clean cracks help improve the smoothness of everyone’s experience.

Bewildered residents wonder why toilet paper is being spread all over town. Toilet paper is used to keep newly-applied tar in smaller cracks and off our shoes, bikes, and cars. Single-ply only.

## A township could not be exactly six miles on each side

Grid corrections : places where North American roads deviate from their otherwise logical grid lines in order to account for the curvature of the Earth. You could drive out there your whole life, de Ruijter realized, and not realize that certain stop signs and intersections exist not because of eccentric real estate deals, but because they are mathematical devices used to help planners wrap a rectilinear planning scheme onto the surface of a spherical planet.

## Whenever there's trouble, they're there on the double.

"On a good day, the street maintenance team tasked by the New York City Department of Transportation with roadway repair might fill 4,000 potholes in eight hours. In an average week, they could resurface 100,000 square yards of road. After Hurricane Sandy, their crews removed 2,500 tons of debris. And every day, on a Tumblr called The Daily Pothole, New Yorkers can take a peek inside the workings of a city system few have likely thought about."

## Pick your plot, worry about the details later.

As Americans, we pick a place to live and then figure out how to get where we need to go. If no way exists, we build it. Roads, arterials, highways, Interstates, and so on. Flexible and distributed transportation networks are really the only solution compatible with that way of thinking. Trains, which rely on a strong central network, never had a chance. We were destined for the automobile all the way back in 1787, when we first decided to carve up the countryside into tidy squares.

## Adding up US subsidies for auto travel with and without the costs of war

In the U.S., motorists do not pay their way. The US government spends more on highways and other auto-related expenses than it receives from auto-related taxes, unlike almost every country in Europe. In a recent report [pdf], Mark Delucchi calculates automobile-related costs and revenues in three different ways and concludes the subsidy is around 20-70 cents per gallon or \$24-105 billion in 2002. But what are automobile-related costs, you ask?

## Antique road trip

One of my joys of going on vacation is to get off the interstate and collect a bit of an old historic road. In California over the weekend we managed to grab a bit of Hwy. 1 aka the Pacific Coast Highway past nature preserves, resorts and neighborhoods. Another goal is to do all of U.S. 50, the initial stages of which were reportedly surveyed by George Washington during his tour in the British Army. Wired has a nice article about how a journalist and a photographer ignored the advice of a Federal Highway Administration spokesperson to take a trip down Route 1 from Maine to Florida.
