If you have sleep apnea, you can still drive trucks, but you have to use a CPAP when you sleep so you don't kill people.
Same reason someone who needs glasses, have to wear glasses to drive.
It's not "random" you just didn't think of it yourself or ask a question.
You just assumed that it was fucking "random" because you didn't know the answer. That's not how fucking life works, if you ask questions you'll find out almost nothing is "random" it's just shit you're too lazy to learn about
Stranger in A Strange Land was called "the hippy bible" for a reason...
It was written in the 1960s tho, so even the "woke" parts can be pretty problematic. That just means society progresses tho. If 60 year old media doesn't have anything problematic in it, it means society has stalled instead of peogressed
Pangea was just a big glob and really inefficient.
You'd want a band around the equator, to maximize sea access to facilitate travel, and prevent a few cultures from isolating other.
Pangea is constant war or a single authoritarian government to keep everyone in line.
A band would lead to coalitions, any one empire just couldn't defend it's whole shoreline and would over extend and collapse and fracture.
