Yep. Let's just decapitate them MotherF*ers and write out the report and call it a day.
Oh, it cut their legs off and not their head? No prob. Somebody will buy them a wheelchair.
I’m guessing it’s less paper work than they’d have to file and less wheels chairs to buy than if someone decided to drive a 7 ton truck at 50mph into an area one of these was protecting like a crowded market, financial district, airport, etc. I’m thinking even full coverage insurance would try to fight paying for your wheelchair though if you knowingly drive into one of these. I’m sure they have a clause somewhere.
There shouldn't be roads if you don't want vehicles. And there shouldn't be people on roads. When is the last time you read about someone driving into an airport other than to park or drop off. Why does a crowded market have rods on the pedestrian side?
Because often festivals and parades are held in closed off city streets? Because vehicle based violence has become an increasingly viable option for terrorists, radicals, and angry jerks? I’m not sure where you live, but where I live and many places I’ve visited tend to have sidewalks right next to roads, humans working on large areas attached to raids for service purposes but not intended for general through traffic etc... so on.
Then use Jersey Barriers to close off the streets temporarily, they are portable and easily moved. . And the solution to the last would be to put the sidewalks next to each other between the buildings and build the roads behind the buildings. Walkway between buildings, roadway behind buildings. If you strung this thing across a street at a festival or parade the crowd would get shrapnel damage.
Jersey barriers are very effective and a great idea. Where they work. Like a toolbox, a programmers repertoire, a clothing store: there are many options for vehicle and crowd control barriers. Jersey barriers weigh 4,000 lbs each, stretch about 10’ and to be fully effective in stopping say- a large truck- must be linked to other barriers. If you notice this is made of lighter, easily stored and transported cables, and has different space requirements. It also can allow pedestrian or other traverse from below if needed, and can be seen through. So there are options and one should select the best one for an application. As for shrapnel- I’d rather a crowd or sensitive structure maybe are hit by shrapnel than are certainly hit by a large vehicle. Short of a sand pit or wall, of a vehicle hits most barriers at high speed there’s shrapnel, and unless you wall off the area shrapnel is a danger.
This is called “the vehicle arrestor” and it is made by a company called Barrier1 in North Carolina. They have a version for boats too, and some other barriers with another cool one being their “missile defense” which is a barrier made for stopping vehicles jumped dukes of hazard style at a building or area.
Sounds good. But there is a reason we phased out most steel highway rails. They cause more harm than good. And I'm pretty sure I have never actually seen a news article discussing a car intentionally jumping at a building "Dukes of Hazzard" style. Might be good for the end of a Drag Strip. Then they could spoon up the remains when the chute doesn't open.
That is the inevitable consequence of physics. That is a 7 ton truck moving 50mph. I’ll let you do the math on how much force is behind that vehicle. If ANYTHING causes something with that much force to suddenly stop that force will go somewhere. Barriers like this are intended as a last resort defense for things we do not want that force transferred to. Sensitive and dangerous equipment like power plants, chemical storage, human beings or places many human beings congregate and could be injured. If that truck were going the reasonable speed at which someone would approach a solid object like a building wall, the damage would not be so severe. In absence of the barricade the vehicle would still collide with said wall and still absorb the force of being slowed from its speed. This is not designed as an ordinary traffic control but to protect and restrict access to at risk sensitive areas and targets.
