"The mess" comes from the fact that 90% of the roads are barely large enough for 2 cars. Yet you see cars, pick up trucks, vans, trucks, bigger trucks and buses everywhere. How about imposing more vehicle size limits on some roads and enforcing it ? Maybe that's the issue, it can never be enforced?
Whenever I find myself stuck and pissed off in traffic I can't help but wonder what's wrong with people driving cars here ? Really I wouldn't want to drive a car even if I was paid $500/h to do it. Do they lean more towards selfishness? ie I want to drive a car so I will drive a car and f everyone. I don't care about being a nuisance and making people stressed, angry and very late everyday. Or do they lean more towards lower intelligence ? ie what's wrong with driving a car in Bali ?
About the world population discussion I remember watching this video in which Elon Musk say the problem is the opposite of what most people think, including smart people.
I remember thinking this is interesting and wanting to find out more about what he's talking about. But then I realized I have much higher priorities than watching interesting yet anxiety provoking videos about things I have no control over anyway.
