There can be several ways to explain this but generally speaking you are right. It shouldn’t go over the speed limit, and under no circumstances should it take the liberty drivers usually take of being within 10% above the limit. I hope no one wrote it that way.

I don't think that's true at all. There was an article posted about the subject a while ago, but the thrust of it was that researchers think they need to do more to make cars behave like (fully attentive) human drivers rather than being weird anomalies that behave in surprising/irritating (to humans) ways if they're going to actually go on the road, and I think that's completely right.

  "(fully attentive) human drivers" probably cause deadly accidents every day, and they certainly behave in surprising/irritating ways. Anyways, a human driver going the speed limit is no hazard, so I fail to see how having self-driving cars follow the limits could be a problem.

    Autonomous cars need to share the road with human drivers, so they should not behave in a way that is surprising to humans, to the extent possible.

Why not? The range between 1-10 MPH over the speed limit is statistically the safest. (Yes, I know, good luck finding a citation for a study I read 20 years ago...) It's hard to argue against the notion that you're safest when you keep up with prevailing traffic. That means that self-driving cars shouldn't be programmed to go slower. Speed limits are usually too low. Often they have nothing to do with engineering or safety considerations, but are primarily revenue-oriented. If the advent of autonomous vehicles forces regulators to listen to the engineers for a change, that will be an unalloyed Good Thing.

  Man, sorry for the downvotes. This link -> http://www.lsp.org/pdf/troopc85thSpeed.pdf http://www.lsp.org/pdf/troopc85thSpeed.pdf doesn't include any references, unfortunately, but the statements are that: -- 55% of drivers regularly exceed the speed limit, meaning that the speed limit represents the 45th percentile speed -- driving between the 50th and 90th percentile speeds is the safest Taken together, driving at the speed limit is significantly unsafe.

    As far as I understand your comment, driving at the speed limit is unsafe because everybody is speeding. Sounds like a self-fulfilling thing. Maybe it would be even safer if the majority would obey the speed limit?

      Did you read the link I posted? Theres lots of empirical data out there that says that drivers drive the same speed on a road, regardless of the posted limit. That speed is based on their judgment of the road - sight lines, shoulder width, sharpness of curves, etc.

        People speed because of poor road design and poor enforcement of speed limits.

        Just curious (and not trying to challenge or be confrontational), how long have you held a driver's license?
    - CamperBob2 9y ago
      And the idea that the speed limit itself is the problem... is there any room in your worldview for that possibility? Why not lower it to 5 MPH on a nationwide basis? Think of all the lives that would save!
