The world’s oldest known joke dates back to 1900 BCE in Sumer and it was...a fart joke.
Here it is: "Something which has never occurred since time immemorial; a young woman did not fart in her husband's lap." I'm thinking the punch line was lost in translation?
(The image above is an example of Sumerian writing from the time period of the fart joke and was recorded for posterity, but it's slightly more sophisticated — it's about medical practices.)
If we used hovercraft instead of wheeled vehicles, we would not have to waste tens of billions every year building and maintaining roads; we would just need a few guardrails here and there to protect landscaping. And no need for spreading salt and brine to melt road ice because the hovercraft would basically treat all surfaces the same, whether lawn or snow or water it would make little difference.
Also, damage from accidents would be negligible, so insurance rates would be minimal.
Not to mention that squashed critters due to tires running over them would be a thing of the past.
So it seems like the Aztecs were ahead of their time.
