    I'm not sure I understand your question. Do all traffic engineers shoot for this percentile? As a base, yes, but that is adjusted by the other variables mentioned like side road access, sidewalks/pedestrian traffic, etc., etc.

    Most traffic laws and safety practices in this country are universal - so what, exactly, do you mean?

    Bad analogy. First of all, gymnastics is a spectacularly dangerous sport. Secondly, I am not aware of a single instance of any of those horrific gymnastics injuries that injured an innocent bystander--and if they have occurred, I bet that they are extremely rare. Third, if you want to solve all the physics equations that correspond to this:


    Including margin of error (which is why this was such a spectacular vault!), then be my guest. Take as much time as you need.




    Do you realize that you are inadvertently making an argument for keeping speed limits low and strictly enforcing them? I think we need to wake up and ask ourselves, as a nation, when is enough enough? When are we going to stop sacrificing 30,000+ people every year on the altar of reckless, careless, and otherwise dangerous driving? And no that does not immediately imply that speed = bad, and thus, less speed = good. We've got to be able to move from point A to point B. The question is what price we're willing to pay to do so.
    The one irreplaceable commodity a person has it time. That is one thing think that can not be bought. But apparently time is irrelevant to you, that you put no value on your time whatsoever. If you have to sit in a box for 1, 2, 5, 10 hour, an extra 100 or 1000 0r 10,000 hours of your life so you are safe and poise no danger to others, you're all for it.

    So, then, you now have justify anyone leaving their home without a compelling reason to do so. If they say in their homes they endanger no now. Endangering others is intolerable to you, right? Thus, a person leaving their house unless truly necessary should be considered criminal reckless endangerment to others.

When you raise the speed limit - say to 75 - those numbers don't drop much unless the road is obviously hazardous at those higher speeds. There will still be X, Y, and Z number of driver speeding - but now driving 80, 85, and 86+. Better to keep the speed lower and risk the ticket than open the gate for driver's who don't have the judgement, experience, etc. to speed in the first place.
    The speed at which a car could really injury a pedestrian is about 15 mph. I gather want the speed limit to be somewhere in that range.

    I'm not sure what you're trying to say here. Highways outlaw pedestrian traffic, so that isn't an issue there.

    Right. I'm honestly curious as to whether this percentile is taken to be fixed (which I'm guessing it is) or if they ever readjust it it.

    Most traffic laws and safety practices in this country are universal - so what, exactly, do you mean?
    I'm talking about the responses to said law. I've been all over the country, and some places such as Arkansas have amazingly slow drivers. For others, such as many Atlantans, the speed limit is only a concept.

    You may dispense with the strawmen and argumenta ad hominem. When you do, we can resume our debate.

    Well, then this whole topic is irrelevant since there also are speed limits. Therefore no speed limiters on cars would ever have any relevancy. No pedestrians are ever on highways because it is illegal and no one never exceeds speed limits because it is illegal. Problem solved as obviously there is no problem.

    If you don't like the actual issue why are you even on this thread? And if you see anyone disagreeing with you as a personal attack then debate forums may not be the best place...


    But I will give you a clue as you may have missed.

    1. Contrary what you may think, people have limited life spans.
    2. The slower a vehicle is going the longer it takes to arrive at a destination.
    3. The longer a person is prohibited from doing what they want or need to do because they are in a vehicle, the less effective lifetime that person has.

    Slower speed limits reduce people's effective lifetimes.

    May not matter to you. You may prefer to sit and stare at a wall in an empty room for all I know. But some people actually have places to go and things to do when they get there.

    Why do so many people live in such constant fear of everything? Do they just stay in their houses because statistically it is safer than going into public and being safe is the singular purpose of life or something?

    If you would just tone down the rhetoric, there is actually an interesting point somewhere in that post. It has to do with the fact, as I have already alluded to, that establishing and enforcing traffic laws has to do with balancing the freedom to travel vs. the right to life. And the answer is not straightforward.
