Look, if you are gonna play Mr. Know It All,
I suggest you do not escalate my point by saying
elusive shaped military explosives are now required for barrier penetration, which you are arguing for my point of concrete over steel. Which explains why bridge cloverleafs prefer more durable concrete over steel.
And yes, I do know jack sh*t, we had lunch just the other day. Lol.
I’m “arguing” that ANYTHING can be destroyed by the proper application of high explosives - steel AND concrete.
Concrete has no lock superiority.
