I think we are missing the point here a little
In a previous employment I worked on barriers installing them up and down the country
Most of the stuff I did was on Bridges where containment was key there were various strengths of barriers avaliable and all rested rigorously down at the mira research facility
The barriers chosen were done so due to various factors like speed, acheavable angle,weight of vehicles on the road and what was underneath
We had barriers that could stop a 44 ton arctic fully laden getting on to a railway line at 56 mph
But we wouldn't put them over small side roads on the motorway where a low containment spec of just a large car would be specd
So basically if you are in a laden van at 3.5 ton or above you will probably be going through if you hit it at a decent speed and angle
It's all about risk vs cost
Most have a design life of 30 years so there is a constant replacement program in place if vehicles get bigger and heavier on average then its very easy to up spec the barriers at point of replacement
In other news for those that have followed my postings before on real life EV ownership
I have sold my model S and a new model 3 face lift is getting delivered tomorrow
And right at this moment I am on my way to collect a C7 I have purchased
In my opinion there is plenty of room for both
Ev for the daily is perfect and a v8 for the weekend
