I have 4 nominees if we start a contest under the Black Hand symbol ... Engineer seat not solid ( on entering cab of loco you walk inside it.) Legs of passengers swing through their clothing Take a seat in train and coat of passenger leaks thru their seat towards my virtual knees Set banner on distant low boundary wall north in yard of L.A Union and then fall through under the track next to you, where you perish as if in Pompei under the ash ... but you have view of objects overlaid above you and solid "ground" as a trench for you to pace about in ... but Alcatraz is San Fran, not L.A ...
I never saw this as a bug tbh, it’s often quite helpful to get in front (like standing up in front of seat) when there’s no way to get round
