Rental Cars and Romantic Comedies

I was intrigued by this anecdote from Stephen Baker’s new book The Numerati:

“What is it about romantic-movie lovers?” Morgan asks, as we sit in his New York office on a darkening summer afternoon. The advertising entrepreneur is flush with details about our ramblings online. He can trace the patterns of our migrations, as if we were swallows or humpback whales, while we move from site to site. Recently he’s become intrigued by the people who click most often on an ad for car rentals. Among them, the largest group had paid a visit to online obituary listings. That makes sense, he says, over the patter of rain against the windows. “Someone dies, so you fly to the funeral and rent a car.” But it’s the second-largest group that has Morgan scratching his head. Romantic-movie lovers. For some reason Morgan can’t fathom, loads of them seem drawn to a banner ad for Alamo Rent A Car.

The reason is later revealed:

I ask him about the correlation he told me about earlier, the one between romantic-movie fans and Alamo Rent A Car. It takes a moment for him to recall it. “Oh yeah. They were off the charts.” Did his researchers, I ask, ever come up with an explanation for it. He nods. “It had to do with weekends. It was Alamo ads promoting “escapes” that attracted the attention of these web surfers, he says. The romantic-movie fans booked leisure rentals, largely for weekend getaways. Perhaps they wanted to act out the kind of scenes that drew them to the cinema. Banners for weekday rentals apparently left them cold.”

Long-Term Parking

Via the Times:

For many expatriate workers in Dubai it was the ultimate symbol of their tax-free wealth: a luxurious car that few could have afforded on the money they earned at home.

Now, faced with crippling debts as a result of their high living and Dubai’s fading fortunes, many expatriates are abandoning their cars at the airport and fleeing home rather than risk jail for defaulting on loans.

Police have found more than 3,000 cars outside Dubai’s international airport in recent months. Most of the cars – four-wheel drives, saloons and “a few” Mercedes – had keys left in the ignition.

Some had used-to-the-limit credit cards in the glove box. Others had notes of apology attached to the windscreen.

“Every day we find more and more cars,” said one senior airport security official, who did not want to be named. “Christmas was the worst – we found more than two dozen on a single day.

A Fine Line

I’m all for stiffer traffic penalties — and much of Costa Rica’s new law is commendable (and tries to treat the corruption issue) — but I did find a particularly curious bit of fine print:

“Other controversial measures include an $82 fine for a taxi or bus driver who insults his passengers.”

One wonders where something like this comes from — is there a rampant plague of offensive bus/taxi drivers? What constitutes an insult (do we know one when we hear one)? Who exactly will decide to declare a citation (maybe armed ‘bus marshals’?) And why $82? (in the U.S. you’d have to tack on a few thousand bucks for emotional pain and suffering).

One of the interesting and rewarding things about putting a book into the world is to witness the myriad and often unexpected ways people engage with it. For example, Jelani Greenidge wonders about the spiritual issues the book, in his opinion, raises — and of course even the Vatican’s Pontifical Council has weighed in on the problems of driver savagery.

Michael Giberson, meanwhile, delightfully salvages a moment of poetry of which I was not even aware.

He writes:

I found a sentence (p. 126) to read nicely as a bit of traffic poetry (I’ve broken the prose sentence into three lines, in the manner of most poetry):

Or the hiccup in heavy traffic that passes through you

might be the echo of someone who, forward in space

and backward in time, did something as simple as change lanes.

He then elaborates:

I particularly like the way the meter has a sort of pulsing flow through the lines until you reach the last two words, which to my ear must both be stressed. A spondee, in poetic terms, that brings the flow of the sentence to a halt, while echoing the “hiccup” at the beginning of the first line.

You might also note the manner in which the syntactic unit “forward in space and backward in time” is broken over two lines, a poetic device called enjambment, which seems appropriate for this found poem about a hiccup in heavy traffic.

The Price of Anarchy Redux

This piece, on the clash between individual routing action and overall network efficiency, generated a ton of discussion of the blogosphere (which tended to treat it as an entirely novel discovery). In an “erratum” published in the latest Physical Review Letters, the authors acknowledge some previously unacknowledged predecessors (e.g., J.G. Wardrop) to their research:

“After the Letter was published, it was suggested that we provide a few additional references about social optima and Nash equilibria in transportation science. The importance of optimum and equilibrium traffic led Wardrop to postulate them as fundamental principles in 1952 [1]. Four years later, equilibrium conditions were described mathematically by Beckmann et al. [2]; see Ref. [3] for a retrospective. An English translation of Braess’s classic paper [4] on paradoxes in equilibrium traffic, together with accompanying comments [5], was published in 2005.

We thank L. S. Nagurney and A. Nagurney for informing us about these publications.
