This argument (while good) won't apply to cars for simple economic reasons. Having a human pilot or subway driver costs 1 marginal person for hundreds of people. Having an extra driver per car costs 1 person per person. I will strongly bet that the two orders of magnitude difference in cost will overcome the bureaucracy. Additionally, once cars become sufficiently advanced, it will be much cheaper to insure a self-driving car than to insure a human. Once the change happens, it will be breathtaking how rapidly it occurs. Social stigmas are hard to sustain towards a large portion of the population. In 2000, if you were wearing a helmet skiing, you were crazy. Now, you're crazy not to. You used to be a loser if you were on a social network. Now you're a loser if you're not. Both these changes happened over perhaps one to three years. Critical mass may only be ~5% of the population. You only need enough to avoid individuals being singled out as odd.

"Social stigmas are hard to sustain towards a large portion of the population." Over 90% of Americans have used illegal drugs, and yet there is still a strong stigma there. http://www.monitoringthefuture.org/pubs/monographs/vol2_2009.pdf http://www.monitoringthefuture.org/pubs/monographs/vol2_2009... (C.f. page 101, as well as the methodology.)

  Your phrasing of that statistic is misleading. What you mean is, "90% of Americans have used illegal drugs or used legal-drugs illegally." When you say "illegal drugs" people think of marijuana, heroin, cocaine, etc. Casually lumping in underage use of alcohol and tobacco is purposefully misleading.

    Does it count underage drinking? I didn't even notice that if it does. Regardless, around 85% of Americans use marijuana alone, so it wouldn't change the statistics by more than one or two percent. So I don't see how that would be misleading.

      85% have used at least once, not "use" marijuana.

      85% sounds pretty wild. Hm, looking at pg 78 of the linked document, it says among people surveyed who were exactly 50 years old when surveyed, graduating in 1977, those who tried marijuana were 82%. 1977 has got to have been the historical peak of high school usage. I notice they don't mention 51 year olds or 49 year olds, they have specifically pulled out this one exact age for this statistic. It then goes on to say that 29-30 yr olds have a 68% "adjusted" lifetime prevalence. What does that mean adjusted? It means the actual number they measured is lower (32% for 19-30 year olds), and they tweaked it upwards because they wanted a bigger number. About this time is where I say a study has too many methodological flaws and should be disregarded.

        "What does that mean adjusted?" It's explained the study. "About this time is where I say a study has too many methodological flaws and should be disregarded." Try actually reading it. It's really not that difficult to understand. The 'maturity recanting effect' section here also gives a brief summary of what they did and why: http://www.erowid.org/psychoactives/statistics/statistics_article2.shtml http://www.erowid.org/psychoactives/statistics/statistics_ar...

        I feel very comfortable stating with 100% certainty that your claim that the study said 85% of all people report being marijuana users (exact words: "around 85% of Americans use marijuana alone") was completely and outrageously inaccurate. It's humorous but a touch sad that you can't admit you were completely and utterly wrong. Lay off the stuff, clear your head, and re-read the report, dude. It's also charming that you cite erowid.org as a reliable unbiased source. I am familiar with the site and have read it. It is a radical pro-drug site.

  There are lots of stigmas against behaviors which are widely considered, well, stupid. Or immoral. Or degenerate. Even if lots of people have tried them (and perhaps still occasionally imbibe). Hypocrisy is demonized. Sometimes rightly, sometimes wrongly.

> Having an extra driver per car costs 1 person per person. If the car has some sort of payload (like a Semi or UPS truck), then this makes total sense. If the human is the payload, then there is no benefit at all. (Well, other than being able to multi-task -- but if you're working from your car, why not just work from home and skip the commute?)

  You can multi-task in areas other than work. You could be reading a book, playing a musical instrument, making phone calls, or even enjoying some recreational refreshments that impair your ability to operate a motor vehicle. Much like taking public transportation to work, it turns commute time into time that can be spent doing something other than paying attention to the commute.

    Recreational refreshment? Another technology revolution that will be driven by the fact, that sex sells?

"Now, you're crazy not to [wear a helmet skiing]" We do not leave in the same world. I mean, really, I am in East asia, not the same world. People do not ski much here, and if they do it is without helmet. I know it is a bit tiring to recall this but it is a good habit to think about the reality of the generalization that one write. What I like on HN is that it is usually not too provincial. Sorry for the nit-thing.

Very interesting! I never thought about the insurance issue. The current systems rates premiums mostly according to personal driving record, right? [1] Hence, if I never drive myself, my premium should only depend on the crash record of that type of robot car. This would also imply, that my premium could raise, because that kind of robot, recently crashed a bit too often. At the same time, I might be able to reduce my premium by installing a software or hardware update. [1] I have a license for years but never owned a car. AFAIK it is not just the drivers record but also the statistical likely hood of a crash, according to gender, age in car. Though, cars today are not rated as 'unsafe' because they are buggy but because they are popular with reckless drivers.
