    Why the hell is that unfortunate? Utilities should be nationalized. ...

    Corporations (and Utilities) are separate from the Government so that they have an incentive to keep an eye on each other. If they are nationalized, then they are all one and there is no one left to keep an eye out.

    Should such behaviors simply be accepted as a sign of the times?

    No more than a thirst for alchol should be accepted as a sign of the times.
    There will always be things that will attract you, but that also harm you. You must have the self-control to resist them, or you will fail.
    But, like many things, they may not be so harmful in moderation. So limit them to a level that you can control. Be aware, though, that your limit might be "zero".

    Most here know, that statistics are not useful if the sample size is below a certain number.
    But, did you know that the statistic can not usefully be -applied- to a group less than that number?

    In other words, statistics can not be applied to individuals. (Unless the samples were all that individual.)

    -That- is what is wrong with "profiling" used wrongly.
    In fact it is the basis for racism. Humans have an instinct to assume the individual in front of them is the same as others that look the same, because that is safer in primitive wild conditions. But it is not a good way to think in civilized times, because it is often wrong.

    The police should treat all people the same, because they can not know what they are facing. They should be polite but watch them carefully. Relaxing if the person looks one way and being tense when they look another way, is not good on either side. A criminal can maskerade as an honest person.

  17. Re:Federal Funding is not contingent on speed limi on Montana Lawmakers Propose 85 Mph Speed Limit On Interstates · · Score: 1

    Making it illegal to pass on the right like on the Autobahn would separate traffic by speed with the fastest traffic always in the far left lane and the slowest traffic always in the far right lane. Separating traffic by speed makes roads safer even with a high difference in speed between the fastest cars and the slowest ones.

    Um ... No.
    That law (as stated here) would not force the slow driver to move to the right. It only prevents the fast driver from passing them. Traffic jam due to one car.

    The way it should be stated is that the slow driver must move to the right. I have seen signs that say "Slower traffic keep right", that seemed to help. 8-)

    Give me a break. This sounds exactly like a political meeting I went to (and I won't name which party) where they spent 30 minutes adding a "to do" item being reducing the speed limits on all roads (interstates, etc.) to a max of 45 miles/hour. Not 55, 45. The main assertions is that vehicles get their best MPG at 35, and if one person is saved, the slower time for everyone is worth it

    I find this hard to believe. I've never heard anybody seriously suggest reducing the speed to 45mph on interstates. I hope you won't be offended if I ask you for a citation.

    South Carolina, about 1969 I think, when the first big Oil Shortage hit and the Federal government started the 55 MPH speed limit. Before the Federal 55 limit, the South Carolina legislature voted to drop the speed limits to 45 MPH and changed all of the highway speed signs (Interstate and local). A few weeks later the Feds made the change to 55 MPH and South Carolina had to change all of the speed signs -again-, at a cost of lots of dollars!

    I was there. 8-)

    ... Or are you asserting that computers do something other than what they are told to do?

    Um ... Yes.

    Even assuming that the programming is perfect, which would be very unlikely, the Ram and CPU cores can have errors due to heat, impacts from subatomic particles and other reasons. The estimated incidence for errors due to particle impacts is about once a year, but even that is often enough to worry about in something like an automobile. Not to mention errors in the design of the hardware.

    But my major concern is in the software, which would be suficiently large that it might be slower than humans to react to dangers. Also at that size the number of bugs will be quite significant, and debugging is not something that usually is taught in school.
