Now, I don't want to start the whole one-heade vs. two-headed, T-junctions vs. roundabouts war (there's another thread for that), but could someone (maybe someone who uses the reddit more?) explain what they mean?
Do they insinuate 4 our of 10 Factorio players use roundabouts / single-headed trains? Is it a joke I'm not getting? Something from a movie, maybe?
Just curious
