Me too ... that's why I'm sitting here in the Yorkshire Dales in the sunshine as opposed to looking at a crappy commute home on Thameslink !

Sounds like the 'Operation Bismarck' that London Underground had to do every year when I worked for them.
Literally take the power off - traction, signalling, comms, the lot. See what dies, what doesn't reboot etc. Used to take ages afterwards going round replacing cctv monitors, resetting clocks etc.
Also kind of begs the question of at what point the car is going to look at the road ahead and decide it can't do that ... ie looks at it's non winter tyres and the snow covered 1:5 descent of Buttertubs pass - and makes the call to wake the meatbag up rather than start sliding into the drystone walls.
Tho not an Audi driver, I've also recently stopped for oncoming traffic rather than drive thru a large puddle.
If I hadn't a couple of pedestrians in Reeth would have been drenched in muddy water and the copper coming the other way would probably have nicked me ...
Anyhow, round here (Dales) a large puddle can be of very uncertain depth and hiding a seriously degraded road surface. If you're slowing enough to take account of those you might as well take a little more time and wait and go round.
My Humber Super Snipe used to work on that basis. Total concentration required to just go in a straight line. Tired steering box, high power steering assist (1960 factory fit) to completely deaden any feedback through the wheel, and crossplies on the road. 2 hrs driving was the limit before mental exhaustion forced a rest stop.
One little side effects is that the local authority would know about a pothole pretty much as soon as it occurs ... and therefor be liable for any damage it causes. At present, if nobody has bothered to report a hole, the LA is not liable as it doesn't know about it and therefor is not negligent in making a timely repair.
"So you need proper training to install Windows updates."
When a Window update can bork things like ActiveX controls in Excel like it managed to last year (and for that matter, about a year before that), what it could do to mission critical legacy systems is anybodies guess - so in answer to your question, yes, you do !
Quote from my manager to his director :
"We are resilient to the same issue with the buttons happening again…
We’re not resilient to another untested emergency IM release which breaks something else…"
Dave 126 : "New cities... Interesting. ”If you want to go there, then I wouldn't start from here" goes the old joke. Can anyone here sketch out a portrait of any recent examples from around the world? "
The only one that springs to mind (and I can't say it's a shining example),
Naypyidaw - the capital of Burma
Back in my Central Line days with London Underground in the mid 1990s we had an intermittent earth that screwed up the signalling for about a month. As it was at Marble Arch it caused havoc with the service. Always used to happen in the AM peaks.
The whole area was cleared of any scrap metal etc, engineers on site overnight, nothing found. Points on the crossover given a thorough going over etc.
Eventually the cause was found - there had been a broken chair screw (a screw that holds to the sleeper the thing that holds the rail) in the past that had snapped below the surface of the sleeper. A new screw had been wound in on top of the old one - pushing it out of the bottom of the sleeper. Over time, the track bed had settled a little, thus meaning that the old screw, only under the weight of a fully laden train (hence the AM peak), just made contact with the iron tunnel segment. As the old screw was in contact with the new screw, that in contact with the chair, and the chair in contact with the rail - through which the current controlling the signalling runs, Bingo, a lovely hidden intermittent earth.
Worked with a guy who used to work for the British Board of Film Classification setting ratings for porn (back in the VHS days). He could be a little weird at times.
Gods alone know what these poor sods would be like after a year of watching the output of extremists, jihadists and other assorted nut jobs.
Re the seal
So? Shunting is Victorian Technology, high speed shunting 1930s. Stopping in ATO under about the max braking you want for non strapped passengers to within 30 cm is 1990s LUL Central Line tech. Inflatable bag seals since gods alone knows when. Think of the carriage end overhanging the wheel arrangement by a couple of feet. Carriage fits within the tunnel to within say 15cm (1890s levels of accuracy for tube trains. Good smooth trackbed surface. The seal doesn't have to do much to hold 1 atmosphere over a 6" gap. Hell it could be carriage mounted.
Stopping takes time anyhow, this leaves the running tunnel empty.
Well, yes, if you like, its an airlock - a train sized and, importantly, train shaped one. But there's nothing complicated about a decently sealing door at each end of a tube. It doesn't even have to be completely airtight. And you don't need all that pumping up / down to atmospheric / running tunnel pressures associated with normal airlocks.
In the 1840s-1850s atmospheric railways were running successfully with a motive force that was an evacuated pipe between the tracks. Ok not hyperloop sized, or pressure, but pulling partial vacuums down to half / third atmospheric pressure over pipes best part of 2 feet in diameter a couple of miles long. This despite said pipe having a slot with a leather seal in the top. Using a 100hp steam engine for the suction pump. Remember - we're not after a hard vacuum.
And all this fuss about airlocks ? Make the stop a loop line. Train comes in, shut doors to tunnel front and back of it. Open vent in loop tunnel - the space round the train is small if the fit is relatively tight so not much air moves due to small volume. Open passenger doors. Close loop tunnel vent. Once all on board, shut passenger doors, open tunnel doors (marginal change to tunnel partial vacuum as air round train is small volume). Whoosh off.
And why are some of you worrying about the train behind. At those timings having only one train in the inter-city section would be a frequency higher than many mainline routes.
Yes, DLR still has Train Captains. They can drive the trains in emergency / fault conditions. They are first line fault diagnosis and repair. They also provide a degree of security and a visible point of contact for customers.
One of the other requirements for "no crew" trains is that the train is easily accessible in emergency situations - which explains the footway in the tunnel on the DLR when it goes into Bank, and which rules out most of the Tube as being driver free.
Another is Platform Edge doors - which rules out any Lines of the Tube where more than one stock shares a platform as the doors don't line up - so forget the Jubilee, and Met, and District / Met and Piccadilly
The only time I use Bing is when I want to bring up a map.
Not only are Bing's aerial shots sometimes more up to date than the Google equivalent, but the BIG bonus is that Bing has proper OS maps in the proper colours - both at Landranger and Explorer level.
And not even the OS site has that.
Wrong - he could still sue in the European Court of Justice, whether we're still in Europe or not - it decides whether European Law is being broken in Europe, irrespective of who is saying it's been broken.
Eg China Air Travel Association in this case : http://www.reuters.com/article/uk-china-eu-emissions-idUSLNE7BP00A20111226
Indeed - no road sense at all. Watched one run along the road in panic beside me as I started to pass it. It then managed to run under the wheels.
I was surprised given that I was on a pushbike at the time.
Thump as it went under front wheel, thump (ii) as it went under back - then it ran up a tree. Tough little buggers too ...
I suspect the conversation went more like this ...
"Hokay" - or whatever 1970s-Mind-Your-Language stereotype reply you prefer.
"Hey, you're on the M4!"
"Pliz ?" - or whatever 1970s-Mind-Your-Language stereotype reply you prefer.
"I wanted Brixton"
"Pliz ?" - or whatever 1970s- ... you get the idea.
"Take the next exit please - I want to go to Brixton"
Why wouldn't it stop quite a few of them - most didn't have an ECU back then, but quite a lot had electronic ignition. My 1979 Chrysler Sunbeam had electronic ignition as standard - and that was certainly not a cutting edge vehicle in any respect. [Yes - I've owned a lot of crap cars, in addition to the above I can lay claim to a Fiat 127, a Morris Ital (1.3 Estate to make matters worse) and a Vauxhall Viva HC]
And the vast majority would have stopped pretty soon after with all the diodes in the alternator fried - though, I concede, not immediately. Only stuff with a dynamo and contact box controlled charging would have been unaffected. [Another aside, have seen the results on a Mini alternator of connecting the battery up backwards (the leads will reach on an estate / van) - several of the diodes hadn't just blown, they'd blown to dust leaving just the little metal legs.]
Are they at it again ?
From "Young Zaphod Plays It Safe" (as far as I am aware the only Hitchhiker's related short story he wrote. https://en.wikipedia.org/wiki/Young_Zaphod_Plays_It_Safe
"Er, Designer People."
"The Sirius Cybernetics Corporation were awarded a huge research grant to design and produce synthetic personalities to order. The results were uniformly disastrous. All the "people" and "personalities" turned out to be amalgams of characteristics which simply could not co-exist in naturally occurring life forms. Most of them were just poor pathetic misfits, but some were deeply, deeply dangerous. Dangerous because they didn't ring alarm bells in other people. They could walk
through situations the way that ghosts walk through walls, because no one spotted the danger.
"The most dangerous of all were three identical ones - they were put in this hold, to be blasted, with this ship, right out of this universe.
They are not evil, in fact they are rather simple and charming. But they are the most dangerous creatures that ever lived because there is nothing they will not do if allowed, and nothing they will not be allowed to do..."
