Google’s driverless cars can’t spot potholes or drive in heavy rain

Guess we’re not going anywhere today, then. Image: public domain.

And it seemed like everything was going so well for Google’s amazing new driverless cars. The first set of prototypes has been tested; they’ve driven over 700,000 miles of US roads; they’ve even created a second generation two-seater car with what looks like a friendly face on the front:

Aww, look at its smiley face.

So you could be forgiven for thinking that Google were on the home straight, and we’d all be chauffeured around in autonomous vehicles before the year was out.

But, it turns out, not so much. The most recent issue of MIT Technology Review has revealed a list of the things the cars can’t yet do, as confirmed by Chris Urmson, director of the Google car team. These range from the mildly problematic  - for example, the cars can’t detect the nature of an obstacle, so would swerve around balls of paper as though they were rocks...

...to the downright concerning. Such as not having been tested in adverse weather conditions such as snow or rain. Or being able to detect open manhole covers or potholes.

Perhaps the most worrying issue, however, is the fact that they still can’t operate on most roads. The cars rely on painstakingly detailed 3D maps, which require multiple visits to streets and analysis by both humans and computers: simply downloading Google Maps won’t cut it. And, since the cars can’t respond to unexpected visual signals, like temporary route changes or new sets of traffic lights, these maps must also be updated constantly. That’s a lot of effort, and so comes at a cost.

Urmson assured the publication, however, that engineers are hard at work on all these issues, and he still hopes the cars will be on roads within the next five years, by the time his 11-year-old son turns 16: “It’s my personal deadline.”

Patently obvious: Which European cities are the most inventive?

The latest instalment of our weekly series, in which we use the Centre for Cities’ data to crunch some of the numbers on Europe’s cities.

Europe is quite a nice place. Though Nigel Farage, the Conservative Party, and anyone who’s noticed that the second syllable of Remain sounds a bit like moan will tell you otherwise, there’s some pretty nice stuff there.

The continent is host to three of the world’s richest countries in absolute terms – France, Germany, and Italy. And if you look at the top twenty countries in terms of national wealth per person – aka GDP per capita – then Europe fills more than half the spots, with twelve entries from Luxembourg in pole position to Belgium in 20th place.  Poland was one of the fastest-growing countries in the world last year. Good for you, Poland.

Croissants are tasty, Belgian beer is part of the Intangible Cultural Heritage of Humanity (apparently), and obscenely beautiful cathedrals are dotted around all over the place. In the extremely dubious language of good old-fashioned colonialism, Europe is the Old World – cultural crucible of the planet, Michelangelo, 1066 and all that.

But you probably don't think of Europe as the great 21st century hive of ingenuity, invention, and world-leading technology. Your mind might instead wander to the sprawling Californian campuses of Facebook and Google; the crammed and jostling skyscraper-shrunken streets of Hong Kong, Jakarta, and Shanghai; the ghostly-white-walled robot laboratories of Japan.

While you’re not wrong on that, you’re not necessarily right either – and looking at the numbers of patent applications to the European Patent Office will tell you that Europe remains a hub of inventive activity.

The first thing you’ll notice is that Eindhoven, in the Netherlands, is really really really inventive.

The data comes rom 2011, when there were roughly 250 patent applications per 100,000 people. That might not sound like a lot, so imagine that number differently. If you were at a very hypothetically statistically perfect school in Eindhoven with 1,000 people (discounting obvious contributory factors like post-education migration), there would be at least two people with EPO patents. Or perhaps just one very inventive person. Either way – think back to your real secondary school. How many patents have its alumni been granted? Yeah. Didn’t think so.

Eindhoven is so far out of the other cities’ league that it’s actually worth discounting it from the data to make the other figures easier to see.

Regensburg, a city with a similar population to Oxford just down the road from Nuremburg in Germany’s Bavaria, comes in second, with 83.8 applications per 100,000 people. Aachen, up near Germany’s northwestern border with the Netherlands and Belgium, follows close behind, and the prestigious university town of Heidelberg – just south of Frankfurt – narrowly takes fourth place.

Grenoble is the first non-Germanic entrant. The city in France’s south-east clocks 80 applications per 100,000, before the Germanic cities storm back in with Darmstadt, Zurich, and Basel in quick succession.

To take a generalisation further, what’s extraordinary is that of the top 20 of these most inventive cities, only four are in countries or areas that do not speak a Germanic language. For our purposes here, I’m excluding the UK (and the English language) from that definition; Grenoble, Cambridge, Lausanne, and St Quentin en Yvelines are the only cities in the top 20 that aren’t in German, Dutch, or Swedish-speaking places.

And if you do include English as a Germanic language – which you probably should – then you’re down to Lausanne and St Quentin en Yvelines as lonely French outposts in the Germanic land of invention. Nobody wants to veer into linguistic-group stereotyping, but there’s something very Vorsprung Durch Technik going on here.

Get rid of all the Germanic-language-speaking nations included in the data (by my count: Great Britain, Germany, Germanic Switzerland, Flemish Belgium, Denmark, the Netherlands) and it’s a very different picture.

France entirely dominates, taking up the first 12 entries prior to a guest appearance from Parma in Italy. Geneva slips in behind, and the Italians romp through with Bologna, Modena, and Ferrara all in the non-Germanic top ten. Weird, huh?

And for the cruel-spirited amongst you, the least inventive cities included in the data were Almería and Jerez de la Frontera in southern Spain, Taranto, Reggio di Calabria, and Palermo in southern Italy, and Czestochowa in southern Poland. Pesky southerners.
