Google Street View is the most audacious data-gathering project ever

Google Street View is an extraordinarily expensive project for a company which normally deals with razor-slim margins. It involves building customised cars, shipping them all over the world, and then hiring drivers to patrol the roads for hours on end.

The eventual plan is to map every street they can (and they mean every - Jon Rafman's 9-eyes is a wonderful collection of weirder pictures taken), an extraordinary project which certainly goes far beyond what makes economic sense. While Street View images of, for example, London's Oxford Street are likely to be regularly checked and probably easily monetiseable, it's hard to imagine what use images of Manitoba, Canada's highway 39 are, beyond bragging rights for the company.

But Adrian Holovaty suggests one reason why Google may have wanted to carry the project to its conclusion: it's nascent driverless car project. Holovaty writes:

Now, I’m realizing the biggest Street View data coup of all: those vehicles are gathering the ultimate training set for driverless cars.

I’m sure this is obvious to people who have followed it more closely, but the realization has really blown my mind. With the goal of photographing and mapping every street in the world, Street View cars must encounter every possible road situation, sort of by definition. The more situations the driverless car knows about, the better the training data, the better the machine-learning algorithms can perform, the more likely it is that the driverless car will work. Brilliant.

Google is, first and foremost, a company build around data-wrangling. Most of the data they get is provided by their users, but some, like the Street View corpus, they have to go out and get. And if they do, it's worth their while to work out as many ways of using that data as possible. The real question is whether they realised once they had all the information that they could use it to teach computers how to drive, or if this has been their cunning plan all along.

Thanks to Robin Sloan for the pointer.

Mister Lizard is not at home to bailiffs – he is eating salmon pâté by the river

Why is it that when people answer the question “What’s the worst thing anyone’s ever said to you?” in the Guardian questionnaire they never say, “You’ve been served”?

Summer’s nearly over. I look at the angle of the sunlight as it strikes the back terrace of the Hovel. I have been here long enough to use the terrace as a gnomon marking the passage of the year. I need, like the protagonists of Withnail and I, to go to the countryside to rejuvenate.

Last week when the Perseids were meant to be in full flow I asked frantically on a social medium for people to chum me along on a midnight walk on Hampstead Heath. In the end my new friends A— and her husband, C—, together with his new friend (whose initial I have forgotten, but he is Australian, if that helps), stepped up to the plate and after a couple at the Flask we went on a wide-ranging tour, which was a bust as far as seeing meteors – or my favourite tree – went, but was still hugely enjoyable. At about 2 am they packed me into an Uber and I went home happy, but I still felt as if I could do with more countryside.

The next few days made me even more anxious to get out of London. There are ominous signs that some serious roadworks are going to be taking place outside my bedroom window any day now. A bailiff came and rang the doorbell and I didn’t have the heart, or the nerve, to say that Nicholas Lezard was not at home at the moment and, is, in fact, on a walking tour of Patagonia now I come to think of it, due back some time next year. I just took the piece of paper into my hands as if it were a chicken come home to roost.

The previous day, presumably the same bailiff had come round and asked if Mr Lizard was in, and my housemate gallantly – and quite truthfully – said “no”. (Why is it that when people answer the question “What’s the worst thing anyone’s ever said to you?” in the Guardian questionnaire they never say, “You’ve been served”? Maybe it’s because they haven’t ever been.) In addition, as I said last week, the cleaning lady is on holiday and the Hovel is starting to look distinctly seedy.

So, then I get a call from a person who once featured quite prominently in this column, some time ago. This person is bored and wants me to go to his or her town and alleviate his or her boredom. This person and I parted company in circumstances that were far from ideal some time ago, and only recently have diplomatic relations been resumed.

It is too late, I say, for me to get on the train now; but when I have reviewed the book I am meant to be reviewing, I will hop on the train tomorrow around noon. And so I do, despite some monkey business from the departures board at King’s Cross, which tells passengers the 12:44 has been cancelled, then hasn’t been, then has, then hasn’t after all, while the 12:14 has slipped away like a thief in the night without telling anyone it was doing so.

I wonder if my return to the town of ——— is wise. As a dog returneth to its vomit, so doth a fool return to his folly. And the burnt hand fears the fire. Look, I say to myself, all we’re doing is going to have a picnic by the river. As we buy our supplies, the stallholder at the market asks if I am my companion’s husband. “No, he’s my picnic buddy,” he or she replies. “Never heard it called that before,” says the stallholder.

And the day passes perfectly pleasantly. We have two bottles of wine, cheese and smoked salmon pâté with crusty bread. People in punts drift past us, with varying degrees of competence. I remember it is A-level results day and call the eldest boy to ask how he’s done. He’s done well enough, it turns out, to get a place at university, though he feels obliged to point out that his results came in exactly a year ago. This is the kind of thing that happens when the number of children you have exceeds your mental bandwidth.

Later on, a porter from the college behind which we are picnicking asks me if I am a member, or an alumni. “Alumnus,” I correct him gently, hoping that this should establish my credentials. He asks for my name, and he radios the porters’ lodge to check my veracity. For some reason it takes him several goes to get my name right.

One of these goes is “Lizard”. We offer him some cheese, but he refuses, on the grounds that he has just had a banana and a cup of tea. I could live in a guest room here, I reflect, at not much higher rent than one pays in London. And the beauty of it is that the police, and presumably bailiffs, have to ask permission to go through the gates.
