Something else to note about bias-ply…no need for directionals! Flip the tire around to any corner and it performs just as poorly as it did on the original location. Radials separate if you run them in one direction and then flip them in the opposite direction. PSAs today are shit scary too! haha
Oh I dunno, there was one about not playing near electricity substations that ended with an exploding child and another voiced by Donald Pleasance, the stuff of nightmares and wet beds
Not to completely derail the thread, but…when I was a child, we played after dark outside without adult supervision, went to the store by ourselves, stayed home (or went outside to play) after school when nobody was home to watch us for hours, and rode bicycles without any helmet/padding (and sometimes in only a bathing suit!), so, yeah. 
We could also ride motorcycles with no helmet, legally, on the street, with other traffic around us (this pretty much ended completely in the US in the 90s)!
Only time I ever went to the US I went to Illinois in 2011.
Seeing all those guys on motorcycles with no helmet on was a bit strange.
