According to the BBC, Addison Lee, the premium private hire and courier service, are planning on self driving taxis, in London, by 2021. Chancellor Philip Hammond said last year he wanted to have "fully driverless cars" without a safety attendant on board in use by 2021, so this is in line with that hope.

BBC Business report of Addison Lee's announcement

Humans are so much better than anyone likes to admit, sure there are 'narrow AI' devices that can beat us at some things,  but overall our understanding of the world and making sense of what we see is in most part so instinctive that we think anything can do it,  unfortunately that is not the case. Would not surprise me if sleazy politicians like Phil Hammond have lots of shares in autonomous car companies and are pushing the tech for personal gain. Politicians do not understand most things,  but they understand money pretty good, and if it comes down to profit or the good of the public,  guess what comes first ?  One of the things Trump supporters like about him is 'that he understands business made his money before he went into politics, most others do it the other way around' (hint - most politicians trained as lawyers or accountants).  MIT and other high tech institutions realise the limitations of the the tech,  as one MIT professor said, 'don't expect your autonomous taxi to turn up if the weather is bad' ( one of the reasons the present trials are carried out in perfectly dry states like Arizona ).

Some people will only consider you an expert if they agree with your point of view or advice,  when you give them advice they don't like they consider you an idiot

By a ratio of 3:1 fatal accidents occur more on rural roads, where speeds are higher, roads are narrower, more twisty and hilly, road surfaces not so good and often covered in leaves or mud - this is the area where autonomous cars could make the most difference ( if they could ever travel above 15mph ), but it is the area where they will be least at home. With hedges and trees scattering back random reflections to sensors, road markings missing or obscured by leaves or mud and roads not cleared of snow. Initially ( and IMHO for a long time ) AV will be restricted to small and well defined city areas, where accidents are normally a lot less serious than in rural areas. Will it be possible for AV to pass on a single track road with passing refuges like normal human controlled cars do all the time ? How about if an AV has to cross a double white line to pass a slow or stopped tractor or vehicle, and how about detecting and safely passing cyclists ?  Just a few on many scenarios that humans take in their stride and hardly need to think about.

Agree with Culzean above. I regularly cross a ford, travel along roads strewn with branches after storms, travel through snowdrifts etc.

How will autonomous cars cope with deep snow? And ice? Badly I suggest..(and one winter morning with literally everything covered with 1cm of shiny ice - trees, walls, the road, signs etc.. breathtakingly beautiful but reflecting light everywhere)

"Companies pursuing automated driving are appealing to cities to build infrastructure that will aid the functioning of their autonomous vehicles. For Aptiv and Lyft’s demo in Las Vegas, traffic lights along the route are equipped with sensors that give the cars extra directive on whether to stop or go"

This article says what I have thought for a long time,  that the roads will have to change to suit AV. Transponders on traffic signals and speed limit signs etc etc - why not just put wires under the road like they have been doing in industry with AV internal logistic trains since early 1980's ...   This is why AV will be limited to certain specific urban areas that have been modified for their needs, and the idea of free roaming AV that can take you from Lands End to John O'Groats remains a distant pipe dream, science fiction that may never become science fact.

Just reading a book about the human brain, first thing that interested me is that humans underwent a massive increase in brain size ( compared to our chimpanzee ancestors ) when they started eating meat ( bring me a 16 ounce T bone I have an exam coming up  lol). The other interesting bit was that in a piece of the human brain the size of a grain of sand there are around a thousand million connections - literally mind blowing.  Most of our brain runs in automatic mode, and the amount of brain we use to carry out 'voluntary' tasks like driving is tiny ( but the background brain is seamlessly processing all the vision and muscle movements in the background).  This is what crude human AI has to compete against.... a massively competent human computer perfected over millions of years of evolution, where the fittest and most able survived.

This makes bad reading for anyone who hates online ads - prepare to be bombarded by advertisments you cannot turn off during your autonomous car journey ( LOL )

This article discusses the present 'AI winter' - as the evangelists of driverless cars realise what a hard act to follow the human brain is..


https://blog.piekniewski.info/2018/02/09/a-v-safety-2018-update/

This article tracks the trends of 'disengagement' ( when auto system has to be overridden  by a human ) and notes that they are not getting any less,  and while not every disengagement is an accident,  but being kind and saying 1 in 10 may well be, it seems the cars still have a long long way to go to match present human safety record.
