They are not a pipe dream in Silicon Valley, and may not be a pipe dream on dedicated highways that only allow automated cars.
 
You are mostly correct, any Google car that lacks manual controls will be grounded during bad weather and/or novel conditions since 'autonomous' parts heavily relies on detailed mapped and predictable environment.

Traditional car makers (e.g. Detroit 3) are not always wrong and in this case Google should not be simply assumed to be correct. Since I was not part of these meetings, I can only form my opinions based on what was reported. Still, there are some things that concern me with Google/Tesla approach to autos:

* Unwillingness to finalize the product is part of Silicon culture. When I buy a car, I expect final product with very rare instance of patching (e.g. recalls) and no instances of altered or added functionality. The fact that when you buy Tesla you are subjected to "patch Tuesday" tinkering greatly worries me.
* No defined model years. With traditional cars you usually know that parts from years X-Y models A-Z are interchangeable. Not so much with Tesla - where mid-model changes are commonplace. What going to happen when 10+ year old Tesla needs a new part? Always buy new, because no two of them are ever the same?
* Used car market. For electric cars it doesn't exists. This means that depreciation on these is largely unknown.

Libertarian market driven approaches of 'perfectly informed' customers having access to 'flexible supply' are only workable on paper. Sure, it would be nice if we could get there, but meanwhile our situation continuing to deteriorate. Time to abandon this quixotic quest.
 
What we need is "mostly works for most people most of the time", and to get there we need policy with teeth that mandates Net Neutrality. Sure, it won't prevent all abuses, but we only need to prevent worst of them and let the rest play out in courts.

Very interesting post, thank you for writing it up.
 
I have a question. Are there guard bands in biological computation (e.g. our brains) ? I was under impression that our cognitive processes (software) are optimized for speed and designed to work with massively parallel but highly unreliable neural hardware.
 
What I am trying to say is that nature performed optimization decided that it is better to be very efficient all the time, and correct some of the time, but also be very good at error checking. While our CPU and OS designers decided that computing devices must be correct all the time, efficient some of the time, and poor at error checking.

+ - Facebook Is Making Us All Live Inside Emotional 'Filter Bubbles'->

But we tend to think of that on a micro level: If your close circle of friends tends to have tattoos, wear polo shirts, or say "chill" a lot, it's quite possible that you'll emulate them over time—and they'll emulate you too.

But what happens on a macro scale, when your friend circle doesn't just include the dozen people you actually hang out with regularly, but also the hundreds or thousands of acquaintances you have online? All of those feeds may seem filled with frivolities from random people (and they are!) but that steady stream of life updates—photos, rants, slang—are probably shaping you more than you think.

A massive Facebook study recently published in PNAS found solid evidence of so-called emotional contagion—emotional states spreading socially, like a virus made of emoji—on the social network."

If you are attempting being rational, then you need to reevaluate your decision making process. With rational approach, cost of ownership paired to a list of features is all you should consider. Optimizing the curve, you eliminate initial depreciation by buying used, and high repair/maintenance by selling the car before it gets too expensive to maintain. The optimum ends up being 2-8 years old car of any reliable car. Why reliable? First, it impacts resale value at 8 years old. Second, it allows it to make it to 8 years old without incurring major repair costs. You can't get any newer than 2 years, there isn't reliable supply of these, and selling before 8 years old leaves you with too short of an ownership to flatten the depreciation curve.

In closing, you might not want to drive that hypothetical lasts-50-years car in 49th year, but it makes cost of year 1 to year 5 cheaper.

Again, I disagree.

Very few people outright buy the car and use it until junk yard. For people that lease resale value directly impacts their payment, less it worth at the end of leas term higher the monthly payment. For people that finance, trade-in value of their last car impacts their payments. In almost all cases original buyer and second-hand buyer are financially tied via 'cost of ownership' concept.

The car is not a software product, and obsolescence is not clear-cut or binary. Nearly all car features, including safety, are tied to original car budget. For example, luxury 5 year old car will likely still have more safety features than 0 year old econobox. That is, you are A LOT more likely to survive a crash in 2009 Mercedes S500 than 2014 Chevy Spark. I can find many examples of 10 year old cars that are still 'feature-complete' with anything that can be found on the road today. Your "obsolete after 5 years" is way, way off and suggests to me you are trying to rationalize your leasing habit.

+ - Century-old drug reverses signs of autism in mice->

Submitted by sciencehabit
sciencehabit (1205606) writes "A single dose of a century-old drug has eliminated autism symptoms in adult mice with an experimental form of the disorder. Originally developed to treat African sleeping sickness, the compound, called suramin, quells a heightened stress response in neurons that researchers believe may underlie some traits of autism. The finding raises the hope that some hallmarks of the disorder may not be permanent, but could be correctable even in adulthood."
