I heard that they are illegal. All cars have to do is go above a certain speed, not too much above the limit, and it destroys the rail. If the rail gets through the car to the driver or any passenger, which is likely, then they are injured - severely.

The thing is they are replacing old ones with new ones which are killing -not speeders, just normal people- so they delayed installing them. It was on the news. http://www.wsbtv.com/news/news/gdot-sticking-guard...
Holy Cow, I've never seen such a think. It looks like a kitchen mandolin.
What does a "kitchen mandolin" look like? The mandolins I know, the cars would bounce off of the strings.
Yes but they removed old & put in new and stopped them for these reasons:
Yes, I agree, as we have plenty of guard rails up and down the Interstate on my commute, as there are so many deep ravines. Cars have veered off plenty before the guard rails were put up. I am thankful with this time change that they are there.
Just above your I posted a comment with links to news sites about how they removed old rails to put in new ones and stopped - they show why.
That is why they started removing them and making them illegal. Driving too slow they were like hitting concrete and there were many injuries; too fast and they crumbled and you died. I believe that dirt/sand would work better;only fast rigs might .
Yeah that's true. That's why research engineers are constantly working on building better ones that solve the problems you mention.
Sure, above the hill it slows a vehicle down due to it losing momentum on the way up. I agree with each of these Beth but they were talking about the ones on our main roads and highways. They were already saying 'illegal in places but still had them.
If you are going fast enough then it does not stop you and if it is metal/steel then it harms you. How about if they make them out of dirt? That would stop about 80% - 90%, if not 100, of people without hurting them - at least not as bad as metal.
They are there as a warning, not stop you physically. If you are stupid enough to smash into one in order to play tag with a train you're likely to wind up dead anyway. The same goes for smashing through a barrier in order to drive over a cliff.
Suppose that your brakes have gone out, or something similar, and you cannot stop. I think that something like two piles of sandbags would be better and do less harm than guard rails, and may be cheaper.
Who knows? You would have to put the sandbags to the test. But sandbags won't stop idiots doing their thing. And sandbags won't show up well enough at night to be a warning.
Of course they would test them. If they can build the pile deep enough it would stop everyone and not harm them, at least not as much. the outside would be made different so they could paint them or something.
Others have come up with the notion that ordinary sandbags would disintegrate with rain and wind after a while and need replacing too often. Glow in the dark sandbags might be too distracting and cause accidents. Reflectors on guard rails are fine.
They stopped installing these new rails for old . Here are 2 links:
There are main supports for the rail which stick up, right? Bike riders, and other travelers without cars, get harmed on those - besides other areas of the rail. What do you think of dirt/sand in their place?
Dirt and sand are temporary as barriers, not very effective and easily washed away.
Maybe somehow they can be kept from washing away. Such as a new type of sand bags.
No idea how they would permanently implement them, but i would imagine it would be safer and cheaper to do
They are always trying to improve and re-invent things these days and the rails are already illegal in some areas. So who knows?
Transportation of any type, people are injured by guard rails. Suppose they replaced them with something better which does the same job but does not injure as bad.
