Railroad crossings are exceptionally dangers ~ mostly because there are trains going through there, but also because trains have the right of way!
Gee, ya think?
And I would add to that, if you see an idiot in front of you who HAS stopped on the tracks, stop your own vehicle far enough back that the idiot has room to back off the tracks if s/he happens to realize what an idiotic thing s/he has done (and noticing you in the rear-view mirror, keeping your distance, just *might* cause the idiot to think about why you might be doing that, and thus realize that sitting on the tracks is an idiotic thing to do).
