Before the Revolutionary War, the American colonies would vote by voice, often at places like carnivals where they may or may not have been drunk by the time voting happened.
To vote, you just called out your choice. As you can imagine, this voting method was very susceptible to corruption!
(I couldn't find an image of pre-Revolutionary War voting, but I thought the one above was interesting — it's a polling booth in 1840s NY!)
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.
