I won't disagree with what you said, but I'll disagree that it's the same point I was making.

My point was that there isn't a technical solution to traffic congestion. You need less fluid or a bigger pipe. What you correctly mention is why a bigger pipe won't work for humans when it does for water.

And out of pure pedantry, I'd disagree purely because my analogy said "non-newtownian liquid" - those don't expand. :P it's more like a hyperactive toddler manically jamming silly putty into a PVC pipe.
