The error in your logic may be in applying what would happen if a crowd of
people suddenly had to go through a narrowing of the path. That would indeed
effect everything past the narrowing. The water is powered by the pressure
pushing it through and this will make the water go faster in the narrow
section so largely negating the sort of effect one would expect by using the
people analogy.

With water the flow is effected by not just the bore of the pipe but by the
length of pipe so a very short narrow section will not effect it as much as
one would think.

Thank you :-)
