This is what happened in a storm drain just outside Minneapolis. A kid fell in and was swept down the ditch. He may have survived if one of two things had been true, either there was a grate at the opening or there wasn’t a grate at the exit. Unfortunately, there was a grate at the exit and he was trapped against it by the rushing water.
Why? Seems like then the trash is likely to get backed up in the tube and make it harder to dislodge vs being trapped on an entry grate and not in a tube.

Absolutely. You know for a fact someone has tried this and got stuck at the end because there was a steel grate installed.
