How will these perform when they get filled with snow or ice or trash?... Maybe on an underground system it would be OK, but I'd guess that the majority of US transit systems are at or above ground.
I think the harsh reality you're missing is that most deaths involving transit/rail come from the blunt force trauma of being struck at speed, not from being dragged underneath. And the vast majority are suicides. Nets won't prevent that.
Out of the city, 60 MPH? All it'll do is slice the ankles off before hitting the person committing suicide...
...and I'm going to end it there.
